Activision has confirmed that development is underway on a new sub‑franchise for the Call of Duty series, intended to run alongside the existing Modern Warfare and Black Ops lines. In an interview with The Game Business, Activision chief marketing officer Tyler Bahl said the company has "already laid the groundwork" for a future title that will become a long‑term branch rather than a one‑off experiment. Bahl also noted that Modern Warfare 4 will incorporate some feedback from the community, while emphasizing that a separate sub‑series is already in progress. The announcement represents a shift from Activision’s recent focus, which has largely centered on the Modern Warfare and Black Ops pillars. During the PS4 era, the franchise operated with a three‑team rotation — Treyarch, Infinity Ward and Sledgehammer — each contributing distinct sub‑franchises. That model narrowed in recent years as development resources concentrated on the two dominant series. The upcoming title could therefore introduce fresh mechanics and concepts. Activision has not disclosed details about the setting, theme or narrative direction of the new sub‑series, nor indicated whether it will revisit concepts from earlier entries such as Advanced Warfare. The company is currently keeping information limited while Modern Warfare 4 approaches its release schedule. KitGuru asked readers what they would like to see from a new Call of Duty sub‑series and whether any discontinued titles might merit a sequel.
