360 will still have at least a 5 million console lead on PS3 by then, that lead is even larger in North America (and its more of a North American game), Microsoft is really building the marketing to this like they did with Halo 3, and 360 owners tend to buy more games per console sold, so it should be no surprise for Gears 2 to sell more.
I think the bigger question is what number of sales are required on each console for them to be considered successful?
