Just before Ghostbusters: Infestation 2 was released on March 23, 2011, Erik Burnham was given the opportunity to pitch an ongoing series. The pitch included 16 issue's worth of Burnham's vision for the series.
On March 30, 2011, an advertisement with art by Dan Schoening hinted at a new monthly comic book series starting in September 2011. The advertisement is an homage to the Ghostbusters' first commercial from Ghostbusters.
On April 21, 2011, a teaser was released that previewed Cover A of Issue One.
On September 7, 2012, an advertisement was released that teased the next arc slated to start later in the month. The image is a logo with a cartoon ghost in crosshairs. The 'Busters' in 'Ghostbusters' is crossed out.
On October 16, 2012, an advertisement for February 2013 titled "The New Ghostbusters" was released. It stated the Ghostbusters were missing and promised an exciting new line-up. In the ad, behind Janine, are photographs of various characters that have appeared so far in the ongoing series.
On October 22, 2013, Tom Waltz posted a new teaser for 2014 titled "Mass Hysteria!" with arrow symbols prevalent in the image. 
On November 12, 2013, Tom Waltz posted a second teaser for "Mass Hysteria!", slated to begin in February 2014, depicting the Ghostbusters, Chicago Ghostbusters, and former Ghost Smashers battling a giant creature.  Ryan Lee later confirmed that was the cover he did for Volume 2 Issue #13. 
On January 28, 2014, IDW posted a third teaser for "Mass Hysteria!" depicting a reunion between Louis Tully and Dana Barrett with their shadows being those of Vinz Clortho and Zuul's respectively. 
On December 21, 2016, Tom Waltz tweeted "Ghostbusters 101" is just the tip of the iceberg and there big plans for Ghostbusters at IDW for 2017 and 2018. Multiple events are in the works. 
The continuity is based on the two movies, Ghostbusters and Ghostbusters II, and Ghostbusters: The Video Game. On October 2, 2011, Erik Burnham clarified the continuity at work for the series.
- The first two movies are definitely canon.
- Burnham cherry-picked from Ghostbusters: The Video Game and fans should "Assume that the events from the game happened... unless you see me contradict them."
Tom Waltz confirms this continuity and the series will also be in continuity to previous IDW issues. The series will take place after the events of Infestation.    The previous series are:
- Ghostbusters: The Other Side (4 issues)
- Ghostbusters: Displaced Aggression (4 issues)
- Ghostbusters: Past, Present, and Future (1 issue)
- Ghostbusters: Tainted Love (1 issue)
- Ghostbusters: Con-Volution (1 issue)
- Ghostbusters: What in Samhain Just Happened?! (1 issue)
- "Guess What's Coming to Dinner?" short story in Ghostbusters: Haunted Holidays trade paperback
- Ghostbusters: Infestation (2 issues)
On October 30, 2011, Tristan Jones stated the series takes place roughly in 1994 but in general, a fictional mid-1990s. On March 2, 2012, Erik Burnham tweeted it is generally a "vague present" but "if it had to be tied to a specific year it'd be 1994-ish." 
On October 30, 2011, Tristan Jones hinted a character appearing in Issue #5 will help give solid verification that the ongoing comic is not in continuity with The Real Ghostbusters and Extreme Ghostbusters. This character turned out to be Kylie Griffin.
After Volume 2 Issue #20, the continuity will continue into a 4 issue mini-series crossover with the Teenage Mutant Ninja Turtles, starting in Teenage Mutant Ninja Turtles/Ghostbusters #1, and after that, the 4 issue mini-series crossover with The Real Ghostbusters starting in Ghostbusters: Get Real #1. The continuity continues into an annual in 2015, a Volume 3 of the ongoing titled Ghostbusters International, a second annual in 2017, a six issue mini-series crossover with the Answer the Call Ghostbusters, starting in Ghostbusters 101 #1, a five issue mini-series sequel crossover with the Teenage Mutant Ninja Turtles, starting in Teenage Mutant Ninja Turtles/Ghostbusters Volume 2 #1, a third annual and 8 issue maxi series in 2018 starting in Ghostbusters Crossing Over #1, and the first issue Ghostbusters 35th Anniversary: Ghostbusters of a 4 issue series in 2019, a 5 issue mini series Transformers/Ghostbusters: Ghosts of Cybertron in June 2019, and a 4 issue mini series in January 2020 starting in Ghostbusters Year One #1.
In terms of the Tobin's Spirit Guide (Insight Editions)'s continuity, Burnham wrote it to function with the IDW Comics canon. As a result, some ghosts from The Real Ghostbusters and Extreme Ghostbusters were tweaked in terms of their back story or just for certain logic to work in the movie/comic sensibility rather than the animation sensibility. Some ghosts that appear in the guide could also appear in an IDW comic in the near future like Samhain. The details about Samhain in the guide would be used by Burnham in the comic. Samhain was planned to appear in the International arc but there wasn't any more room as the writing went on.  
On November 16, 2013, it was revealed Louis Tully was no longer off-limits from being used and would be appearing the Mass Hysteria! arc.  The 30th anniversary was a selling point in getting Louis used during Mass Hysteria! in credit to Tom Waltz and Cindy at Sony.  Conditions came with using Louis Tully, there couldn't be a giant character change; like having three kids and being the governor of South Carolina. 
On June 26, 2016, during the Crossrip Podcast Episode 227, Erik Burnham revealed he also wasn't allowed to use Slimer like how he was utilized on The Real Ghostbusters. 
On December 11, 2011, Erik Burnham elaborated that each trade collection will collect four issues. If sales does well, IDW is more likely to approve a longer storyline (and consequently longer trades).
On January 4, 2012, Tristan Jones announced his PCOC material will be included in the trade collections.
On November 17, 2019, Erik Burnham recalled last he heard, the fifth hardcover collection will tentatively come out in fall 2020.
From start to finish, when Erik Burnham starts writing the script to when Tom Waltz is finished and sends the comic to the printers, an issue takes about 5–6 weeks to be completed. At times, they can be working as far in advance as two months/issues ahead. Burnham spends a week or less to write the script. Dan Schoening and Luis Delgado spend about 3.5 weeks on art.
On July 5, 2011, Erik Burnham offered a status update on scripts: Issue #1 is done, #2 is done, approved, and being drawn, #3 is waiting on revision notes, and #4 is being generated.
On November 21, 2011, Erik Burnham tweeted his daily work: "I have 5 pages to write, the next Ghostbusters arc plot to work on, some rewrites, and a short 200 word piece" and later 
On November 22, 2011, Erik Burnham replied the scripts up to Issue #6 are completely done.
On June 14, 2012, Erik Burnham provided a script update. The story for Issues #13-15 is "pretty well set" and he is currently "mulling" #16.
On June 16, 2012, Erik Burnham posted a peek at some Ghostbusters plotting.
Not Approved Pitches
On April 11, 2013, Jones revealed he pitched a Ghostbusters annual featuring a John Tobin story that would be the thrust of the issue just like "The Man Who Sought Death" in Ghostbusters #8 and Dan Schoening, Luis Delgado, and Erik Burnham would tell a contemporary story alongside it, but the pitch was not greenlit. 
On August 14, 2014, Jones revealed the pitched annual would have expanded on Tobin's encounter with the Grundel, seen briefly in Volume 1 Issue #8. He also revealed a new pitch that involves trees, witchcraft, cults, and a life at stake. 
On January 21, 2018, in an interview, Erik Burnham revealed he originally pitched a smaller story but Tom Waltz overruled him to do Crossing Over instead.
On March 7, 2018, Erik Burnham revealed the smaller story he pitched to precede Crossing Over was a series of one-shots focusing on a bust by each team before the crossover.
On October 20, 2019, Erik Burnham revealed the only real conflicting idea shot down by Sony/Ghost Corps was around the time of the 2016 movie. At the time, an idea that was pitched was also going to be in the movie so it was shot down but it wound up not being in the movie's final cut.
On April 6, 2012, Erik Burnham revealed he had a story planned that dealt with Egon and Janine but the Haunted America arc developed. This story may appear at the end of the year.
On November 12, 2012, Erik Burnham said "maybe in a backup, one day" there could be a story through the point of view of PCOC.
On April 1, 2013, Erik Burnham revealed he was thinking about using a djinn for an upcoming arc.
On August 21, 2013, Erik Burnham said there will probably be more Extreme Ghostbusters characters in the future. 
On January 27, 2014, Erik Evensen hinted he and Erik Burnham have ideas for more stories.

On March 18, 2015, Erik Burnham hinted there are ideas about other competing companies like the Ghost Smashers. 
On April 20, 2015, in a posted interview, Tom Waltz hinted there are big plans for Janine, Kylie, and Melanie in future stories and hopes some more of the characters from Sanctum of Slime appear in the pages of the comic. 
On December 14, 2015, in an interview, Erik Burnham revealed at one time there was a story where in the Ray's Spirit Guide was helping as an act of good faith to get the Ghostbusters' trust then eventually their help. He may do the story some day. 
On September 27, 2017, Erik Burnham indicated the next few arcs will continue to be shorter runs (rather than another volume of the ongoing series). 
On October 31, 2017, during a Turtles Tuesday live stream, Tom Waltz confirmed they hope to do a third Teenage Mutant Ninja Turtles/Ghostbusters crossover. 
On April 10, 2018, Erik Burnham revealed he had an idea for a ghost similar to the Vathek from Extreme Ghostbusters except it was tied to language, though, random sounds instead of writing. He wrote it for something else but he was given the wrong info, looked into the wrong thing, and so adapted something he didn't need to but if he gets a chance, it will be used in a Ghostbusters story.
On June 8, 2018, in an interview recorded at North Carolina Comic Con in March, Tom Waltz mentioned there are other properties IDW is actively talking with Ghost Corps about crossing over with the Ghostbusters and it's a matter of legalities.
On November 7, 2018, during a podcast interview, Erik Burnham revealed the third crossover between the Ghostbusters and Ninja Turtles would involve the Ghostbusters visiting the Turtles' dimension. He also revealed there is a pitch that he and Tom Waltz liked, that hasn't been approved yet, that involves the introduction of a new Ecto vehicle, a submarine.
On February 15, 2019, Erik Burnham revealed he has submitted several more pitches and one of them is a crossover. He hinted, "I am fighting to get a battle in the book with a very specific ghost that ain't named Casper!"
On May 30, 2019, Erik Burnham revealed there is a pitch being currently looked at with extra scrutiny to make sure nothing is replicated from the 2020 movie.
On June 10, 2019, Erik Burnham confirmed he pitched a crossover with Beetlejuice.
On October 20, 2019, Erik Burnham confirmed a sequel to Transformers/Ghostbusters has been talked about. The teaser line at the end of Issue #5 is in part meant to try and nudge Hasbro to agree to a sequel.
Ghostbusters Year One
On April 3, 2019, in a "Three Questions..." mini-interview with Tom Waltz included at the end of Ghostbusters 35th Anniversary Ghostbusters, Tom Waltz teased there was "something fun planned for October (Halloween time!)" with the creative team of Erik Burnham, Dan Schoening, and Luis Delgado.

On October 4, 2019, Tom Waltz made a cryptic post tagging Erik Burnham, Dan Schoening, Luis Delgado, and Tim Lattie and revealing four covers featuring each of the original Ghostbusters and nods to the first movie.
On October 21, 2019, Tom Waltz posted another teaser image featuring each of the original Ghostbusters.
On November 4, 2019, Erik Burnham confirmed each issue will focus on a story told by one of the four Ghostbusters and they will largely stand on their own sort of like a series of microseries. Each issue will tell its own between-beat moments set during the first movie.
On January 14, 2020, Dan Schoening posted a combined version of the A covers.
On January 20, 2020, Erik Burnham teased there is a subtle hint at the subpoena the Ghostbusters get hit with. He initially pitched it as the ending to the mini-series but it was decided against.
On January 27, 2020, in an interview, it was revealed the idea for Year One evolved from Tom Waltz wanting to do a book with the title "Ghostwriter" which had an author interviewing the Ghostbusters, and it morphed from there.
Transformers/Ghostbusters: Ghosts of Cybertron
On December 11, 2018, Tom Waltz posted 4 rough thumbs of the prime Ghostbusters and hinted June 2019.
On December 17, 2018, Erik Burnham he lobbied for something else with Ghostbusters and had to decline writing all four issues of the 35th anniversary mini-series because of the next release scheduled for June 2019. He hinted it was "pretty big" and it's been kept a secret since San Diego Comic Con 2018.
On January 29, 2019, Tom Waltz teased wip art of Slimer from a cover, wip art of the Firehouse, confirmed Erik Burnham, Dan Schoening, and Luis Delgado are the creative team, Part 1 is in June, and the title of the arc includes "Ghosts of" in it.

On January 30, 2019, Tom Waltz teased more wip art from a different artist.
On February 18, 2019, a logline for the series reveals "When the Transformers pick up on a strange Cybertronian signal emanating from Earth, they travel to the planet only to discover that the threat waiting for them there is something that Venkman, Spengler, Stantz, and Zeddemore are perfectly suited to help them take on." Variant cover partially previewed and an edited version of Dan Schoening's connected covers was revealed. Other cover artists include Paulina Ganucheau, Nick Roche, and Alex Milne. Tom Waltz revealed the title is "Transformers/Ghostbusters: Ghosts of Cybertron" and Ectotron is an Autobot.

On February 22, 2019, Tom Waltz posted the individual versions of the covers by Dan Schoening and Luis Delgado except for Issue #3.
On February 27, 2019, in an interview with the crew, Erik Burnham described Ectotron as "a bit of a nerd," "almost as far out there for the Autobots as the Ghostbusters were from other academics here on Earth", "kind of uptight," and he's teased by the other Autobots but he will "loosen up" by the end of the story. The mini series starts in a way no one will expect. They will be dealing with some ghostly common enemies.
On March 24, 2019, in an interview, Erik Burnham revealed Ectotron is a nerd in the same way that Ray Stantz is a nerd. Ectotron is a little defensive about his title, and he doesn't get sent out on missions too often but in this story Optimus Prime is sending him out to investigate a signal he discovered so the mission means so much to him. Burnham is a couple issues into writing the mini-series. Starscream steals the spotlight. When he wrote the outline, Burnham kept the cast small. After he saw the connecting covers, he added a few more like Grimlock but it may be for just a panel.
On May 17, 2019, an early sketch of Ectotron was revealed.
On June 28, 2019, during an interview recorded earlier in the month, Erik Burnham revealed the Ectotron and Optimus Prime toys were in develop 1.5 to 2 years ago then as the anniversary got closer, a comic was suggested, other Transformers ghosts will be appearing, and Grimlock will say, "Grimlock afraid of no ghost."
On July 22, 2019, Erik Burnham posted the completed panel of Grimlock he teased in June.
On September 5, 2019, Erik Burnham decided Earl Hammond's portrayl of Mumm-Ra on "Thundercats" as the voice of Kremzeek.
Ghostbusters 35th Anniversary
On June 14, 2018, Erik Burnham hinted there is still a desire to do a third Teenage Mutant Ninja Turtles/Ghostbusters crossover but the next story or stories after Crossing Over will not have a "dimensional-travel component." He and Tom Waltz just talked the other night and worked up a "great idea."  
On July 18, 2018, Erik Burnham estimated the next Ghostbusters story after Crossing Over wouldn't come out until next year. He hinted at a story he wanted to do that involved the core four Ghostbusters with Kylie and possible Melanie.  
On December 11, 2018, Tom Waltz put together 2019 publishing plans for Ghostbusters. He posted 4 rough thumbs of the prime Ghostbusters and hinted June 2019.

On December 14, 2018, Tom Waltz posted more information and covers about the series. In celebration of the 35th Anniversary, the mini-series is a four issue weekly event in April 2019, featuring 4 different Ghostbusters teams in adventures written and illustrated by 4 different creative teams.

On November 19, 2017, Erik Burnham added Melanie Ortiz would appear. 
On December 19, 2017, the premise was revealed. Jillian Holtzmann and Ron Alexander are jealous of the main branch's teleportation unit so they independently build their own but their versions inadvertently unleashes every ghost ever contained in their Containment Units. Some of the fan-requested ghosts didn't make the cut while some now have a beefed-up role. Cover B and RI of Issue #1 was revealed as a tentative release date of March 28, 2018. 
On January 20, 2018, Erik Burnham confirmed Rachel Unglighter would at least appear on a Ghostbusters Crossing Over #3 cover but wouldn't confirm if she'll appear in the story proper or not.  Burnham also admitted he would have to cut down some character's appearances to cameos. 
On January 21, 2018, in an interview, Erik Burnham revealed he originally pitched a smaller story but Tom Waltz overruled him to do Crossing Over first. He likens Crossing Over to a mix of DC's Crisis on Infinite Earths and Marvel's Secret Wars. Dan Schoening teases there will be new ghosts.

On March 21, 2018, Erik Burnham hinted Crossing Over "follows up on a thread from an earlier comic story."  Burnham, in an interview, revealed that first the story was just going to be a mix and match of the Ghostbusters heading off to recapture ghosts who had escaped from the Containment Unit and Egon has a "babbly" explanation for why this needs to be done. Burnham then started thinking of other ways to play with it and give it some personal stakes. He came up with two things that would give it the right heft, and how they would affect things emotionally.

On July 11, 2016, Erik Burnham teased he and Tom Waltz meet up at San Diego Comic Con and will think up some ideas for a possible sequel to the Teenage Mutant Ninja Turtles/Ghostbusters mini-series. 
On April 8, 2017, Erik Burnham admitted bringing back the Collectors has come up in conversation. 
On May 31, 2017, in an interview the night before, Erik Burnham and Dan Schoening admitted the next story arc after 101 is not yet set. A couple of ideas have been suggested. The next arc depends on which is greenlit first. 
On July 20, 2017, a sequel to Teenage Mutant Ninja Turtles/Ghostbusters was announced at the Ghostbusters 101 panel during San Diego Comic Con. Burnham, Waltz, and Schoening were confirmed. Pablo Tunica, Tadd Galusha, Mark Torres and C.P. Wilson III will also contribute art. The story begins "when an old adversary traps the Turtles in a ghost dimension, as old adversaries are wont to do. However, all hope is not lost for our Heroes in Half-Shell, as New York City’s resident experts on all things spooky quickly answer the call." Waltz confirmed the story will affect both series going forward. Burnham revealed they didn't use any of their past ideas for the sequel, villains from both universes will appear, and there will be more one-on-one scenes among the teams. Cover A of the first issue was also revealed. It is set to release on November 1, 2017.  IDW posted a photo from the panel showing another possible variant cover of the teams attacking a giant entity.  Burnham confirmed it is a weekly series and is five issues total. 
On July 21, 2017, Bobby Curnow confirmed IDW took on the project earlier in the year. 
On August 17, 2017, Erik Burnham saw some pages. 
On September 8, 2017, Erik Burnham teased "expect the unexpected". 
On October 31, 2017, on the weekly Turtles Tuesday, Tom Waltz mentioned one difference from the first crossover is that this sequel would go more into the interpersonal relationships. Like personalities will team up and some you wouldn't expect would help others.  Pre-exisiting characters from a certain canon of one of the franchises will appear.  Erik Burnham added he finally got to use his 'Ghostbusturtles' pun.  This crossover takes place immediately after Teenage Mutant Ninja Turtles #75. Overall, it takes place between Issue #75 and #76. 
On November 2, 2017, in an interview, Tadd Galusha revealed Issues #2 to #4 has interior art from Dan Schoening and all the guest artists. Galusha, for example, did 4 pages in one issue and 5 pages in another. 
On November 10, 2017, in an interview, Erik Burnham and Tom Waltz revealed the genesis of the 5 week event. Nickelodeon had plans in store for the Ninja Turtles in 2018 and asked if the mini-series could be released in 2017. Bobby Curnow suggested a 5 week event to meet the deadline. While driving from western Minnesota to Fargo, Burnham talked to Waltz on the phone about picking what villains to use. Shredder came up as a potential but Waltz wasn't interested and almost immediately suggested Darius Dun.   
On December 12, 2017, Dan Schoening confirmed the Cover A for Issue #2 to #5 combines into one image. 
On December 21, 2016, the March solicitations revealed a new six issue series titled "Ghostbusters 101" that centered on the original Ghostbusters going back to teaching but their first batch of students poke around in the Firehouse and set in motion the merging of their universe and the 2016 Movie universe. The two teams team up to make things right again. The 32 page first issue features variants by Tim Lattie and Erica Henderson, as well as retailer incentive variants with photo covers of both movie casts. The first regular cover has Peter Venkman, a new character, and Erin Gilbert with a map of New York City in the background with reference to Alnitak, Alnilam, and Mintaka of Orion's Belt. There will be six-interconnected covers by Dan Schoening and Luis Delgado.  Erik Burnham clarified the new character on the regular cover was not Roland Jackson.  Burnham mused he might have to rename the character since Dan Schoening chose to draw Roland.  The cover done by Tim Lattie was also revealed. Burnham commented it was a story requested by both the fans and Ghost Corps.  So far, 18 characters are involved in the series.  Ivan Reitman commented he always wanted to meld the two worlds and thinks it will be fun and thinks it will be important in the future to bring it back as a single universe.  Burnham confirmed the series would be six issues total. 
On December 22, 2016, Erik Burnham clarified it is a mini series. 
On January 9, 2017, Erica Henderson poster a teaser of a cover she was inking. 
On January 19, 2017, in an interview, it was revealed the bones of 101 were born during San Diego Comic Con 2016 between Erik Burnham and Tom Waltz. It was going to be a smaller story, with the guys straight-up teaching their trade in between busts. Ghost Corps suggested introducing the Answer The Call (ATC) cast to the multiverse. The title of the mini series was suggested by Waltz since it centers on students learning the basics of ghostbusting and the ATC cast learning more about other dimensions. The ATC team will both take it as a rude shock and a cause for relief. 101 starts with the students Ray has decided to start teaching and they're made aware of the interdimensional technology the Ghostbusters have been experimenting with. They decide to play with it themselves and that leads to the problem at hand. 
On January 20, 2017, Erik Burnham revealed he was written two issues of Ghostbusters 101 so far. 
On January 26, 2017, Tom Waltz posted an image of all six regular covers combined into one. 
On March 10, 2017, Erik Burnham revealed Ghost Corps asked for redesigns of the ATC team to stay away from actor likenesses. Dan Schoening provided a lot of versions with and without.  Schoening's first pass on Abby was almost exact. 
On March 20, 2017, in an interview, Erik Burnham revealed the fourth student is Garrett Parker, son of one of Peter Venkman's old psych classmates. Cait, Zoe and Evan show newly arrived Garrett the Interspatial Teleportation Unit when something goes wrong and the dimensions of the Prime and ATC Ghostbusters starts to overlap. That's way too dangerous to be allowed to continue, and the two teams are looking to fix it, once they all meet. Burnham is currently writing Issue #4. 
On March 22, 2017, in an interview, Erik Burnham hinted an error in the teleportation unit's operation allows for an event that starts to cause another universe to drift. Dan Schoening admitted he didn't know who the antagonist was yet but hinted a ghost doesn't feel all herself like something is missing. Burnham hinted we may see the ATC team again in the future like with The Real Ghostbuster's Egon in Ghostbusters International. He also confirmed the ATC team will recognize the prime team as some people they met in the events of the 2016 movie and in fact just wrote that scene. 
On May 26, 2017, Erik Burnham confirmed the overlap of dimensions doesn't happen all at once. 
On November 7, 2018, during a podcast interview, Dan Schoening revealed it took about 10 tries to nail down the looks of the Answer The Call team.

On August 2, 2014, Erik Burnham revealed the reason for the end of ongoing isn't sales related citing conversations at San Diego Comic Con 2014. Burnham also commented he and Dan Schoening will stick around and a Volume 3 might happen but it isn't set in stone yet. 
On August 5, 2014, in an interview, Tom Waltz hinted the events of the Teenage Mutant Ninja Turtles/Ghostbusters mini-series will matter and will rear their heads in future stories of both franchises. 
On August 13, 2014, Tristan Jones revealed there is a vague chance that he might be writing and drawing a six (or so) issue miniseries in 2015. 
On November 11, 2014, Tom Waltz confirmed the recent news of Paul Feig rebooting Ghostbusters had nothing to do with the end of the ongoing series nor was it cancelled by Sony. Stopping the ongoing series was a decision made by IDW based on dwindling sales and timing. In terms of timing, Issue #20 was deemed a logical point to stop with the Teenage Mutant Ninja Turtles Ghostbusters crossover taking place soon after. The crossover is also aimed to bring more attention to Ghostbusters comics. Waltz further stated other things are in the works and his ultimate goal is a Volume 3 of the ongoing series. 
On July 12, 2015, Erik Burnham announced there will be a Volume Three coming in 2016. Also returning will be Dan Schoening and Luis Delgado. 
On July 16, 2015, Erik Burnham revealed Volume Three is tentatively set to begin in Spring 2016 around April. 
On July 23, 2015, when asked about the use of witches, Erik Burnham hinted he "had an aim to do something for Volume 3", but the crew "went with another tack instead to start." 
On August 12, 2015, Erik Burnham stated there were no more crossovers plans for the near future.  He also hinted IDW is considering going to five issues per trade paperback. If it happens, he would start capping story arcs at five instead of four issues or, at most, where an arc would have a mid-point break. Sales and pre-orders are and always be a factor. 
On August 13, 2015, Erik Burnham revealed he initially pitched 'a year or so' worth of issues for Volume Three, with the first six months more specifically fleshed out. 
On October 9, 2015, a new series titled Ghostbusters International was announced. Erik Burnham confirmed it is the new ongoing series. The title might or might not revert back to just "Ghostbusters" like with Volume 2 in the case of it starting off being titled "New Ghostbusters."   
On November 16, 2015, Erik Burnham announced there will be back up content. They are "Haunted America" incident reports as written by Special Agent Melanie Ortiz based on Corin Howell's variant covers. 
On November 18, 2015, Erik Burnham confirmed Jenny Moran, Kylie Griffin, and Melanie Ortiz will be back in Volume 3. We might see Chicago again. He also corrected an error in solicits, it is Volume 3 of the ongoing series. It isn't a mini series. 
On December 14, 2015, in an interview, Erik Burnham clarified the Firehouse isn't going anywhere and the damage done from the battle with Proteus frees up Dan Schoening to redesign interiors at his discretion.  For the Haunted America back ups, Burnham mocked up an FBI Incident Report for Melanie Ortiz to fill out. He hopes to evolve the format. He also confirmed Ortiz will return to the main story proper.  Burnham has one new Ghostbuster in mind. He or she will be an original character and not taken from the cartoons or games. Any more new Ghostbusters would have to happen organically. 
On December 16, 2015, Dan Schoening noted the regular covers are inspired by travel posters. 
On December 29, 2015, Erik Burnham announced he and Tom Waltz put together some 'pretty crazy ideas' for Ghostbusters. 
On January 7, 2016, in an interview, Erik Burnham stated Volume 3 begins shortly after the events of the annual. The Firehouse is still being repaired so Janine set up shop in the Warehouse. The team taking on international cases will be a rotating cast. Potential locations that might appear in future stories include Japan, Iceland, Germany, Ireland, Russia, and India. Gabriel Rodriguez made a pretty good case for Chile. The cases could be for a scene, for an issue, or for several issues. For the first few issues, the team going abroad will be Winston, Peter, and Ray. 
On January 22, 2016, in an interview, Erik Burnham revealed he first wrote up and submitted notes and ideas for Ghostbusters International around April or May 2015. 
On January 26, 2016, Erik Burnham hinted he was writing about Paris in Ghostbusters. 
On April 22, 2016, in a podcast recorded earlier in the month, Erik Burnham confirmed the "International" subtitle would stay until the overarching story is done. The Chile idea is being saved for later because of how the story shaped up. Later this year, there will be a little surprise callback to Ghostbusters Get Real. 
On April 29, 2016, Erik Burnham stated the current storyline is basically a year long arc. 
On May 2, 2016, Erik Burnham confirmed Iceland after Paris and Ireland. 
On May 9, 2016, Erik Burnham reiterated there are no plans to recreate an alternate version of Extreme Ghostbusters in the IDW ongoing series. 
On June 8, 2016, Erik Burnham admitted he had an idea for a cameo of The Real Ghostbusters. 
On June 26, 2016, during the Crossrip Podcast Episode 227, Erik Burnham hinted there is more dramatic material coming up in International. 
On September 23, 2016, Erik Burnham confirmed there would be more International after the second annual. 
On October 19, 2016, Erik Burnham hinted after the annual, there will be "stuff with me and stuff not." 
On October 26, 2016, Erik Burnham confirmed Issue #11 is the last issue of the International series but reaffirmed there will be more Ghostbusters after it, the Annual 2017 included. 
On July 12, 2015, Erik Burnham announced there will be in annual in Fall 2015 involving himself, Dan Schoening, Luis Delgado and guest creators.  Schoening added it would be around 48 pages.

Ghostbusters Get Real
On March 9, 2015, Chris Ryall cryptically teased there would be news about the comic announced at WonderCon taking place April 3 to April 5. 
On March 13, 2015, Tom Waltz posted an obscured image of several Ghostbusters and Slimers, only saying more information will be revealed soon. 
On March 18, 2015, Erik Burnham posted an image combining all four Regular Covers.  Burnham noted to tell the characters apart, like Peter for example, he would use "Prime Peter" and "Real Peter" then hinted "Real Peter" has his favorite line in the mini series so far.  Burnham confirmed the mini series is canon and takes place some point after the TMNT/Ghostbusters crossover.  In an interview, Burnham hinted readers should rewatch "Janine Melnitz, Ghostbuster" for clues on the mini series. 
On April 8, 2015, from an interview recorded prior, Erik Burnham revealed the story in the mini-series was not the original idea for the crossover. He pitched a 48 page annual initially but Tom Waltz asked Burnham to make it into a four issue mini-series. The story takes place during "Janine Melnitz, Ghostbuster" in between when Proteus zaps the Ghostbusters outside of Rockefeller and when Janine sees them trapped in one of Proteus' mirrors. In the mini-series, the Real Ghostbusters end up in the IDW universe and think they're back home. They enter the Firehouse, go upstairs and run into the other Ghostbusters team. The story revolves on Proteus capturing the Real Ghostbusters and returning to that point in the animated episode. To sync the episode with the comic further, there is a page that takes dialogue from the episode. The idea for the four regular covers connecting into one image came about independently at the same time. Burnham and Waltz were talking about doing connected covers then Schoening, unaware of their plans, also proposed the idea. 
On April 20, 2015, in a posted interview, Tom Waltz teased there will be many fun cameos from throughout Ghostbusters lore. 
On July 16, 2015, Dan Schoening posted an unlettered panel with Slimer from The Real Ghostbusters. 
On July 23, 2015, Erik Burnham confirmed realities other than the ones with the Extreme Ghostbusters and Sanctum of Slime junior team will appear in the mini series. 
On August 12, 2015, Erik Burnham revealed Get Real was an idea considered in case the TMNT/Ghostbusters crossover wasn't greenlit. 
On June 23, 2014, Tristan Jones summarized a Supanova Expo panel on Sunday where Chris Ryall hinted there will be some "pretty big news" regarding the Ghostbusters comics will be released at San Diego Comic Con 2014 next month. 
On July 15, 2014, IDW Publishing issued a press release revealing the new mini series in conjunction with both franchises' 30th anniversaries.  IDW's October checklist revealed there will be a variant cover by Kevin Eastman. 
On July 18, 2014, Erik Burnham reaffirmed this story is a continuation of the ongoing series' canon. 
On July 25, 2014, in an interview, Erik Burnham revealed Donatello has access to Fugitoid's inter-dimensional transporter plans and tries to build one for himself. He does and it works. It sends the Turtles to the right location in New York, but the wrong New York entirely. The four Turtles, Casey, April, the Ghostbusters, Janine Melnitz and Kylie Griffin will appear. There will be a cameo here and there. Tom Waltz has a plan for the "TMNT" series so he and Burnham mined the idea for the villain from that continuity. The villain is connected to another Turtles character and is trapped in a dimensional portal; when he's set free (in the Ghostbusters universe) and he has some decidedly ghost-like abilities. 
On August 5, 2014, in an interview, Tom Waltz and Erik Burnham provided some hints of what to expect in the mini-series: the Ghostbusters and TMNT will be put through the wringer, "a brand new villain from the TMNT’s ancient past," "classic super-team meet-up confusion," "some very geeky science talk" between Egon and Donatello, and a scene where Michelangelo sees Slimer for the first time. 
On August 15, 2014, in an interview, Erik Burnham expanded on working directly with Tom Waltz on the scripts. They got the plot hammered out, got input from Teenage Mutant Ninja Turtles editor Bobby Curnow, Burnham did the first draft, Waltz did a pass, and lastly Burnham makes any tweaks not related specifically Waltz and Curnow's threads for the Teenage Mutant Ninja Turtles ongoing series. Burnham cites he and Waltz came up with the idea of this crossover at San Diego Comic Con 2012 but were thinking about it in general for years. 
On August 27, 2014, Dan Schoening revealed he tweaked the designs of the Teenage Mutant Ninja Turtles so that Raphael is the bulkiest, Michelangelo is smaller than the rest, and Donatello has a bigger cranium than the others. 
On September 6, 2014, Dan Schoening posted his design for Donatello, his favorite Ninja Turtle. 
On September 7, 2014, Dan Schoening posted his design for Michelangelo. 
On September 10, 2014, Dan Schoening posted first designs for Casey Jones but noted this won't be the final version seen in the mini-series. 
On September 12, 2014, Dan Schoening posted a design for Splinter. 
On November 1, 2014, Erik Burnham stated the crossover series takes place a few months after the events of the "Mass Hysteria!" arc. 
On November 18, 2014, Erik Burnham revealed he started the miniseries thinking Egon and Donatello would drive the story. 
On February 7, 2015, Dan Schoening posted rough concept designs for Chi-You. 
On December 14, 2015, in an interview, Erik Burnham revealed that back in when the skeleton of the crossover was conceived, it was much more an Egon and Donatello story. 
On October 30, 2011, Tristan Jones hinted a character, Kylie Griffin, appearing Issue #5 will appear again in the year one slate of comics. Given there is a year two and three, there will be future appearances of this character. There will be an Extreme Ghostbusters-esque situation, but more like the Rookie from The Video Game. Basically, there could be extra people around to help like Janine throwing on a jumpsuit in the Real Ghostbusters.
On September 5, 2012, Erik Burnham tweeted "Plotting Ghostbusters future." 
On September 6, 2012, in an interview with Behind the Pages, Erik Burnham revealed another upcoming story he is plotting currently is not in the original 16 issue pitch.
On October 3, 2012, Erik Burnham hinted the appearance of the Rookie was initially an attempt to seed one thing, but a new storyline in 2013 has changed that. 
On October 14, 2012, Erik Burnham teased that as part of some research for one of two stories starting off the series' run in 2013, he might have looked up The Real Ghostbusters. 
On November 13, 2012, Erik Burnham announced his current goal is to have the second volume surpass the first and make it at least to Issue #20. 
On February 20, 2013, Erik Burnham revealed he plans to continue using the New Ghostbusters team as a support unit after Volume 2's first story arc. 
On April 24, 2013, Erik Burnham announced he's having fun researching ghosts for the next arc. He considered a Scandinavian and South American ones but nixed it for various reasons. Burnham is also looking up African lore and Voodoo.  
On June 22, 2013, Erik Burnham revealed the Chicago faction of Ghostbusters "will be popping up here and there." 
On October 9, 2013, Erik Burnham teased there will be more Rookie and Ron stories. 
On November 7, 2013, Erik Burnham revealed another issue had been approved. 
On August 28, 2012, Erik Burnham revealed he may do a Ghostbusters "replacements" team story one day but for now it was only in the stack of possibilities.
On November 10, 2012, Erik Burnham confirmed "The New Ghostbusters" is the first story arc of 2013.
On November 12, 2012, Erik Burnham confirmed Jack Hardemeyer will appear in the comic soon as a member of PCOC. Ron Alexander will play as more of a jerk than Walter Peck but a techie like Egon. Kylie will be sort of a blend of Ray and Egon. Pagan was not originally planned to appear but will now make occasional cameos in panels. One of the ghosts will be based on mythology and another sort of based on one from The Real Ghostbusters. Janine is on the team because of Peck. Peck will explain "to a surly deputy mayor why Janine is completely indispensable." 
On November 14, 2012, IDW issued a press release that revealed the arc involves the Ghostbusters are kidnapped by demons from another dimension, leading to a new group to don the Proton Packs to deal with New York's supernatural problems and rescue their predecessors. Burnham further hinted the story is split between new team and original team but with more focus on the new.
On November 15, 2012, Erik Burnham clarified the New Ghostbusters would be wearing full jumpsuits in Issue #1, the shorts in #2, and jumpsuits in #3. The shorts is part of a gag about working in retail.
On December 18, 2012, Erik Burnham hinted Idulnas is not working on behalf of Gozer and is trying to get revenge on his own behalf. He may or may not be as powerful enough to act directly anymore. Burnham also confirmed not to expect to see the Stay Puft Marshmallow Man or Gozer or anything else from the Gozerian pantheon. Dan Schoening "requested a riff on something" as the next threat.
On January 4, 2013, Erik Burnham hinted he is considering using the core of the last story from his original pitch for volume two.
On January 18, 2013, in an interview Erik Burnham revealed once the Ghostbusters return home there will be a "host of personal complications for the guys to deal with going forward." Melanie Ortiz is very Winston-like; she's from law enforcement and is the most on-point of the group. Janine is as unflappable as Venkman, will be compassionate, worries about the people she cares for, and, she's a rock. Kylie is the go-to for supernatural information and a mix of both Egon and Ray studying and recalling so much of the oddities of the world. Ron Alexanderwill be a mix of the technical sides of Egon and Ray—very clever with mechanical things, but he is still a jerk so he will be more of a love-to-hate character than Walter Peck ever was. The big difference from the original group will be they don't have the same humorous shorthand and charisma as the originals.
On January 21, 2013, Erik Burnham revealed the Ghostbusters will return to New York before the end of the arc.
On February 3, 2013, Erik Burnham hinted Volume Two will start off "jumping ahead in time" from the end of Issue #16.
On February 12, 2013, in an interview, Erik Burnham hinted the characters who make up this replacement team will not all be leaving the book when the originals return to New York, set up the potential for a villain, and has planted the seeds for the originals to make more problems for themselves because of the solutions they choose — like that time Ray decided on the Stay-Puft Marshmallow Man as the form of ultimate destruction. In another interview, Burnham noted the task of protecting New York City is more forced on the replacements without much of a choice in the matter.
On March 1, 2013, Erik Burnham teased Issue #3 and #4 each will have a panel "that is going to drop some jaws." 
On March 7, 2013, Erik Burnham, in a Crossing the Streams roundtable recorded in February, revealed the New Ghostbusters concept was conceived around September 2012.
On March 8, 2013, Erik Burnham revealed when he was first writing Melanie Ortiz and Ron Alexander in Volume One, he had the intention of bringing them back but hadn't conceived the New Ghostbusters arc yet. At the time, Ron was going to think of another scheme and Melanie would be brought back just for fun since she had good chemistry with Peter. Jenny Moran was initially going to be the fourth New Ghostbusters but someone with tech experience was needed so she was cut.
Issues #1-4 Back Up
On September 30, 2012, Erik Burnham hinted there are talks about a back up story that would start in February 2013.
On November 13, 2012, Erik Burnham revealed the first arc of Volume Two ("The New Ghostbusters") will also have new backup feature taking the place of the PCOC files. The first 8 page story will be serialized in 2 pages per issue in the first arc. The story has been requested by fans and editors for a while now, with the Ghostbusters being indirect in this backup and "something from a ghost's POV" 
On November 14, 2012, IDW Publishing issued a press release that revealed the back up is an all-new Real Ghostbusters story written and drawn by Erik Burnham. Burnham confirmed Slimer, Egon from The Real Ghostbusters, and "the whole nine" will appear. It will be "a fun little romp" following a ghost after it is stored in the Containment Unit.
On November 16, 2012, Erik Burnham, in an interview, revealed the Real Ghostbusters story would also have the captured ghost "meet some familiar faces" in the Containment Unit.
On January 4, 2013, Erik Burnham revealed Tristan Jones was offered the Real Ghostbusters back up first.
On March 24, 2013, Erik Burnham announced he just got some new pages in from Luis Delgado.
On March 1, 2013, Erik Burnham also teased he and Dan Schoening have "crazy plans" for #5-8.
On March 8, 2013, Erik Burnham revealed Kylie Griffin and Janine Melnitz would definitely appear in #5-8 Ghostbusting in a way.
On March 13, 2013, Erik Burnham hinted #5-8 will involve Janine facing consequences from The New Ghostbusters Part 3, Kylie will, in no uncertain circumstances, be out 'Busting, Melanie will have gone back to New Mexico, but the FBI just won't be the same for her, and Ron was almost killed off but something else was decided with him.

The arc will "bring in characters we haven't seen in the book before, a few nods to the past, every character who has worn a proton pack during our run, and to top it all off, a major change to the life of one of the boys" and has "an enemy that won’t be beaten by concentrating crossed proton streams in a single location" so "everyone who has ever worn a proton pack into the story to help." Burnham compares past arcs to the scope of a television show while Mass Hysteria! will be more of a movie event.

Hopefully it comes across..."  He also has seen only seen two scripts and an overall story.
