I think some people are being really unfair to Infinity Ward. They once made really good games, CoD 4 has a 94 rating from critics and an 8.6 from users on Metacritic. Yeah, they started letting Activision have too much control of the franchise, and yes, most of the studio is gone now. But the new Infinity Ward seems eager to prove themselves and make up prior disappointments to fans. We've got a new engine with better graphics, something people have been asking for for several games now. The leak awhile back which seems to be legitimate, (because the leaker knew the Ghosts title more than a month in advance), said that they were adding new gameplay mechanics like leaning around corners, sliding, and prone rolling, that they were working on somewhat larger maps (but still small enough to keep the arcade shooter feel), and that they were even working on limited destructible environments in multiplayer (limited so that idiots with rpg's couldn't destroy whole important sections of the map).
