GameCube only managed around 21 million if I am not mistaken.
It's still tracking a couple million below gamecube (even below dreamcast).
It is more underpowered and has less third party support than the GameCube had during its lifespan.
Its biggest game came out and it can only manage to do 60k in a week.
Almost all of its high selling franchises are already on the platform (just missing Smash Bros)
Smash Bros is also on 3DS.
Japan is a smaller market now than ever before.
The New Zelda is cartoon which most zelda fans dislike.
Will probably have a shorter lifespan than the GameCube due to it not being as powerful as the competition and being much cheaper.
Online lags far behind than the competition.
Nintendo so expect essentially zero advertising.
Wii U is being discontinued in some major retailers in the US just like Vita
I see no way the Wii U can outsell gamecube. If anything the Wii U will hit 17 million. What do you think?
