Okay this has to be revived because of the Slim. But here's the totals of what they are now.
PS2 PS3
USA - 21,372k <> USA - 9,590k
Japan - 11,477k <> Japan - 3,640k
Others - 16,242k <> Others - 11,560k
Total - 49,091k <> Total - 24,790k
PS2 vs PS3 = -24,301k
I think I did that right.
Edit: All of crazzymans original numbers are gone because he's permabanned :(
