the importance of 3d mario will play a huge role for Wii U

[Mythmaker1]

I imagine the game will be of quality. I just don't think it will make much difference.

I'd estimate that a 3D Mario game will sell between 1.25 and 1.75 million systems, total, lifetime. The other people who might buy it either already have a Wii U or are waiting for something else.
