The press conference said theres only a small team of devs working on it, they refered to it as an indie game. Dice are still working on BF4 and beginning production for BF5/whatever it will be.
I think most new FPS games are going down the pan, Call of Duty Advanced Warfare?!? Why not a WaW or CoD 4 remake? Ghosts was a risk so i personally think AV will be the last mainstream CoD game
