Came out earlier so people bought it before Wii/PS3. Then they had their friends play it, they bought one, continued around like that.. now a bunch of people have a 360 in N.A so other friends want to get a system to play them online. Which they can't with another system (obv) so they have to get a 360. My guess is majority rules.
I don't think that happened in Europe since nearly everyone has a PS2 and had no reason to get a 360.
