MikeB - no they don't. DMC was a game that was 100% on the PS2 last gen, and the Xbox never recieved a DMC game, or anything close to it.
Yet the 360 version outsold it - despite selling oh-so much more software. Isn't it wierd that the PS3 failed to have any other game in the top-10, and the X360 had 5 games?
And I say this in respect to the fact that GTA was actually on the Xbox, despite being ported late, and still sold OK.
Back from the dead, I'm afraid.
