First of all what's a failure for the Wii? Coming in last? Well the GameCube was Nintendo lowest selling console ever and it was still quite profitable. It's all but certain the Wii will outsell the GameCube. I think if Nintendo came in a strong third Nintendo would concider that a success. In my opinion as far as worldwide sales I can't see it coming in worse than second anyway. Either the PS3 or 360 will break out and either come close to matching Wii number or surprass it eventually. More likely that will be the PS3. There's no way I can see in such direct competition both outsell the Wii.
