RE5 already sold better (this week)
HAWX
Major League 2K9
COD5 (wayyyyyyyyyy more! 2.000.000 MORE!)
Skate 2
GTA4 (just 1.500.000 more..... LOL)
I will give you SF4, but let's WAIT some more weeks. But COD5 (I don't even need to talk about others) is enough to overcome SF4 difference.
And you can see software total here:

And you have to count with Japan, some games are for the Japanese, and that games sell better on the PS3 because of the installed base. That's why I think PS3 fans are fanboys, they just don't want to see the truth.
