Call of Duty 2021 is set for a fall release according to Daniel Alegre in an Activision earnings call. Alegre is the President and Chief Operating Officer at Activision Blizzard. Sledgehammer will be the developer and the game will have a campaign, co-op, and multiplayer. In the call, it was mentioned it would be integrated into the current Call of Duty system, so a Warzone partnership like in Cold War is likely.
The game will be built for next-gen, so expect a graphical upgrade for PlayStation 5 and Xbox Series X owners.
