I think there are 3 companies working on it. The remnants of Infinity Ward along with Sledgehammer Games (some of the dudes made Dead Space) are doing the campaign. Raven Software are working on the multiplayer. Take a look at their recent games. Marvel Ultimate Alliance is the only one that interested me. They have me doubting their multiplayer. With that whole Infinity Ward fallout and different people working on this game it has me less than confident it will be even close to MW2 or even as good as Black Ops especially since they're rushing to get it done.
I am fucking STOKED on this. I'm a purist when it come to CoD; Modern Warfare series or bust. Black Ops was such a letdown and I'm really bored with farming mats for my professions in WoW. I need a return to FPSs.
Looks like they just ripped off Battlefield 3, judging from the trailer. Here comes another dressed-up corridor shooter from CoD, I can't wait not to buy it. DICE is going to eat these clowns alive and I'm going to support them in their endeavour.
