I think we could see first week sales on 360 of around 2 million, and the PS3 version just shy of 1 million.
At the end of it all, the PS3 version will be at around 5 million, the 360 10-11 million.
As for the PC, its launch probably be lower (around 300-500k), but it'll settle around similar numbers to the PS3
So, we're looking at ~3.25m first week, ~20m lifetime.
Seeing as we won't have any Halo/Gran Turismo this year (well, this side of the pacific), this will probably be the big Christmas game.
