Between Warzone, Black Ops Cold War, the mobile game, and even 2019's Modern Warfare, the Call of Duty franchise is bigger than it's ever been. As such, with several successful titles under it, all of them turning profits, it's no surprise to hear that Activision wants to see this success be repeated with its other franchises.
In a recent earnings call, as reported on by IGN, Activision highlighted how the Call of Duty series has multiple entry points for players - premium, mobile, and free-to-play - and how it believes this is what has bolstered the series' success. As such, this is the template it wants to use with other titles. CEO Bobby Kotick even added that it will attempt to grow its audiences to upwards of a billion players.
It's not entirely clear how Activision will implement this template with other franchises. One possibility is that, given the success of Call of Duty: Warzone and its free-to-play model, fans can expect to see future games adopt a similar model. In fact, there are already examples of this, such as with the Crash Bandicoot: On the Run mobile game. Said game is free-to-play but managed to generate $700,000 in its first week of release.
As for which specific franchises will be receiving focus, that is up in the air for the time being. Activision does have an impressive library between its own IPs and Blizzard's, which covers the likes of World of Warcraft and Overwatch. In fact, Call of Duty's success could affect Overwatch 2's development. For the time being, however, it arguably feels as if Activision is completely preoccupied with Call of Duty. This does make sense but it's been generating a lot of negative feedback from certain members of the community.
As it stands, at least nine of Activision's studios are actively working on Call of Duty. While Sledgehammer Games is developing a new entry for later this year, the likes of Infinity Ward, Treyarch, and Raven Software continue to support the current titles, with even more being dragged in to help as well.
Most recently, Toys for Bob, the studio behind the Spyro Reignited Trilogy and Crash Bandicoot 4: It's About Time, announced it would be working on Warzone too. This was met with swathes of disappointment and anger from fans, leading to assumptions that the studio would no longer be able to helm its own games and that the Crash and Spyro franchises had fallen back into limbo.
