Remember when people said Wii would not even outsell Gamecube. That it would never outsell PS3 (in context to Sony being a Juggernaut with PS1-PS2 domination).

I also remember when people said DS would be the next Virtual Boy.

Do I think it will outsell Wii? No. But you never count out Nintendo. They often surprise.
