@Ebon Raven Software actually worked on MW3's multiplayer while Sledgehammer and what's left of Infinity Ward (seeing as 38 employees left after Vince and Jason were fired) worked on single-player. And that is the reason why MW3 isn't as fun as Black Ops or MW2 in my opinion. MW3 is alright it got really boring very quickly.
