Wii U to pull a 3DS?

[alrightiwill]

I unfortunately don't think that MK8 will boost Wii U sales by as much as people are hoping. A sad truth is that a lot of people who want to play MK8 already have a Wii U. I hope I am wrong but if I recall correctly the last Mario game failed to even outsell Knack or increase Wii U sales significantly.
