Anywhere from 450 to 600 at launch if I had to guess.
Looks decent, though it can't compete with Xbox and PS3 because none of my friends will be buying a new 500 dollar console for a couple extra useless features and in my opinion stuffty first party games.
I'm not too big on Zelda, Smash Bros, or Luigis Homo mansion.
But Mario and that flying fox was decent.
