Wii imo.
pimpcoop, the Ps3 only has 15 mil sellers. Most of its games are crap and that's why only 15 of them are mil sellers. Same with 360. Only 41 games are worth playing and the rest are crap.
*i can do that too.* (that's not what i think just proving your point wrong.)
Damn things have changed since 2009 began. Here are my new visions for the end of the generation.
Wii: 135 mil
Ps3: 85 mil
360: 60 mil
