PS3 is not a very good comparison to PS2 at all!!!!!! It won't reach PS2's success. PS2 got good press and great sales. The way your info is layed out, your making it look like PS3 will beat PS2. It doesn't compare saleswise.
It would've been more interesting to compare Wii to PS2!!!!! (Now that is a fight!)
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
