Is it CoD? I'm guessing they might need to add another dev to the rotation next gen.
I could see it being a CoD, but not a mainline CoD but a standalone Battle Royale game instead. If Activision were to do that it would take some pressure off the 3 main developers as they'd no longer have to make a Battle Royale mode for all their games (lets be real here, no matter what Activision and Treyarch tells us the reason BO4's campaign no longer exists is because they needed that team to quickly throw together Blackout), and they could release it as the ultimate GaaS Call of Duty BR with years of updates and tie-in content with the yearly CoD releases, they could maybe even make it f2p. A f2p Call of Duty BR game with maps, guns, characters etc. from various time periods and futuristic universes with years of ongoing support could be a massive success.
