Zelda Wii wont sell 15million. The best selling Zelda ever was the monster Ocarina of Time at ~7million, and thats the "best game of all time". I set predictions for Zelda Wii at 11million max, thanks to the massive Wii install base and anticipation of "hardcore" games on the system. Think what Twilight Princess would have done with 65million users instead of 30million.
