well 150 million of playstation could exist, but not 150 million users, millions of playstations are defective (30-50 million) and are many playstations redesigned like psone and ps2 slim (50- 70 millions) i think the real userbase of the playstation (ps1 or ps2) are 60 - 70 millions and if the ps2 users go to wii they have 60-70 million users, nintendo need a wii- lite to reach the 100 million mark, but maybe the new market help.
