it will be still very successul as long as another shooter franchise similiar to cod can't take all the multiplayer fans away. so, if there won't be a huge success for a shooter similair to cod at release of the consoles i don't see how another shooter franchise could beat cod then.
cod will be there from day one, i'm sure about that and they will directly start to get all of those people to play their game, sales of the next games come almost from alone then because all those players will replace their old cod against a new one.
