Errrr, Volbound, what? SMSu isn't what made Nintendo lose the last round. Graphics are what made Sony and Microsoft win it. And aside from graphical quality and games, there weren't many differences between the three. To a casual gamer, the prettiness of the PS2 and Xbox, Xbox Live, etc., made the GameCube look like the worst choice. Some all-system gamers here might say it was. It's understandable that the GameCube didn't sell as well as its competition.
On the other hand, Wii offers new things and is way cheaper than the 360 or PS3, so it's understandable that Nintendo is winning this round. It's appealing to non-gamers and non gamers' mothers. That's what business is about. Having the book with the best cover. The GameCube wasn't necessarily lame, but the cover didn't say much for it. The Wii, on the other hand, has "buy me" written all over it, even without the superior graphics--the gameplay is far different from the others', and people like it.
