Give Treyarch 3 years to actualy work on something rather than having stuff finished in half a year (how long has it been since MW3's release anyway?) and they might be able to make a classic (or fail because they are too used to making stuff in short time, although it atleast seems like they're trying to inovate in the C.O.D franchise with the little time they have) I think they ended up with the wrong publisher.
(My experience with Treyarch: World at War and Black Ops, campaigns were interesting, nothing too rememarable but then they had less than a year to finish their stuff)
