I cannot see it happening as Nintendo will win this generation comfortably and we all know that Nintendo systems sell Nintendo games best.
Neither the 360 or PS3 have the install base to sell a 10 million game.
Halo3 will probably hit 10 million WW and GTA4 might hit 10 million between the 360 and PS3 in one region.
Its a long shot but if M$ decided to release Halo 4 on the 360 rather than leaving it for their next console and it was released Xmas 2010 then it might have a remote chance.
