mario kart sold like 5 million on a 23 million userbase. by spring 2008, wii would probably beat that number. gt3 sold 13.88 million on a 120 million userbase. it's obvious that mkwii will beat that when the ps3's gt5 if the userbase for ps3 by spring 08 will probably be 13 million.
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
