The creators

I heard Raven Games was making it. If you don't know what that is they created the Armored Core series. Armored core is like a robot shooting game with awesome artillery, so i bet modern warfare 3 is going to have alot of heavy weapons!!!

Ohh dang, my bad, Sledgehammer games and infinity ward are working on single player and co-op, and raven software (not games) is working on multiplayer. So this has nothing to do with armored core. Never heard of Raven Software but they better make multi-player worth playing.
