wow cant believe all of you are downplaying the 360 version of the game just cause of Japan.
In America 360 has a giant lead
In Europe the PS3 and 360 games sell on par with maybe a little bit of an edge to the PS3, but not much
Japan does not matter much, they both do horrible there and as a vg market it really is the worst of the major markets.
I think the 360 version will ultimately sell more than the PS3 version.
