Nevermore on 22 March 2013
Unless both Microsoft and Sony came to Activision and offered them a monumental sack of money, enough to replace the profits of a skipped current-gen launch of a CoD game, there is no way in hell that this is gonna happen. I could see MS having the cash and motivation to do this, however Sony is in no financial position for this kind of deal.
In all likelihood, the game will just come out on all platforms, both current and next gen, with the question still left open whether it will launch on current and next-gen at the same time.
