The next MarioKart game will be MarioKart 3DS (not final name) for the 3DS, but Nintendo hasn't announced its release date.
Of course, Nintendo.
No Mariokart 2, but there is a Mariokart 7. Unfortunately, it's only for 3DS. Sir/Madam, I think this is a very good time to suggest to Nintendo to make an Mariokart 2.
next date of release for a new Nintendo game?

Mariokart 3DS
Yes, there is currently a new Mario Kart in the works for Nintendo's new hand held system: the Nintendo 3DS.

Considering the fact that Nintendo is trying to keep Arceus a secret and the fact that it's not techniquely released yet, they'll probably release it within the next year.
As of E3 2011 it's due out next winter.
