Mario Kart Wii sales depends on Wii sales 
it will have an attach rate of 25-30% atleast during Wii's lifetime so MK Wii could easily hit 25-30 million.
attach rate just now is 30% and I don't think it will just drop down too 10%
If it isn't turnbased it isn't worth playing

And shepherds we shall be,
For Thee, my Lord, for Thee. Power hath descended forth from Thy hand, That our feet may swiftly carry out Thy command. So we shall flow a river forth to Thee And teeming with souls shall it ever be. In Nomine Patris, et Filii, et Spiritūs Sancti. -----The Boondock Saints
