Previously the schedule had Sledgehammer and Raven set to develop 2020's Call of Duty title, but according to sources close to Kotaku, there have been some tensions between the two studios. For several years, development has hopped between having Sledgehammer, Treyarch, and Infinity Ward as lead studios, to facilitate annual releases.
However, Kotaku's report suggests that this has changed, partly as a result of recent leadership changes within Sledgehammer and disagreements between the studio and Raven.
The big Call of Duty news over the weekend was of course the Kotaku expose from Jason Schreier concerning the troubled development of Call of Duty 2020.
Furthermore, the Kotaku report goes on to say that next year's Call of Duty will feature a single player campaign, and it'll take place during the Cold War. Advanced Warfare was released by Sledgehammer in 2014, followed by Treyarch's Black Ops III in 2015 and Infinity Ward's Infinite Warfare in 2016.
Allegedly Activision are looking into the possibility of using some sort of free-to-play model for the game in the years ahead. The sources indicated that both staffs argued frequently over the past year.
And according to the E3 organisers, Infinity Ward will be discussing the new Call of Duty in a panel at the Coliseum event.
The latest installment of the Black ops series, Call of Duty: Black Ops 4, chose to go against the grain from usual Call of Duty game by removing campaign mode completely and replacing it with a new battle royale game mode, Blackout for fans to experience. Raven and Sledgehammer had been working on next year's Call of Duty title, which was to be set during the Cold War, with at least some of the game's story set in Vietnam.
With all of the above to consider, being a Call of Duty developer doesn't sound like a super-fun gig. Two people familiar with the project described it as a mess. It's hard to say at this point, especially since Call of Duty 2019 has yet to be officially revealed to the public, but we should find out within the next couple of years.
It's unclear how this change will impact the Call of Duty franchise moving forward.
