thinking about it, isn't this not that big of a problem for activision? realistically, the next game from IW would have been at least 2011. by then they already have two or three call of duty games from other studios. this new studio the old guys formed probably won't have a game for a long time, right? they're basically starting from scratch. didn't MW2 use their own engine? even if they use something else (like id tech 5, ue3, cryengine 3) it would still mostly be starting from the beginning. short term Activision won't stop pushing the franchise IW built, and long term, who knows if whatever respawn will do will be relevant in 2+ years.
