x360:
1 Halo 3 10.32m
2 Call of Duty 4: Modern Warfare 7.88m
3 Grand Theft Auto IV 7.28m
+3M Halo 3 over GTAIV
FPS are more popular on x360.

PS3:
1 Grand Theft Auto IV - 5.91m
2 Call of Duty 4: Modern Warfare - 4.72m
+3M GT5 over GTA4

And racing games(GT > Halo) were more popular on PlayStation +1M GT5 sales,
that is 10M+ in worst case.

What? You sure are good at maths. :)
