I kinda think Nintendo needs this game for next Christmas.

3D Mario even if EAD Tokyo can get it is not enough of a big deal.

Smash Bros. is probably near where being done and neither is Zelda (not that Nintendo should bank on that franchise either). Maybe a Donkey Kong Country game could be ready, but with 2D Mario and Rayman already being pushed hard on the system, I think the machine probably needs something else.

Mario Kart ... they should just beef up the staff and make sure it's out by next December.

Also they can milk DLC by way of DLC packs for retro courses and battle maps for a long time too.

10m+

You're definitely right that Mario Kart would make a huge splash. But if Nintendo can release Super Mario Universe, Wii Sports 3, the Monolith Soft IP, and the game from Retro in Q3 and Q4 next year, then Mario Kart and Smash Bros. could wait until 2014. Of course that's a BIG if, but that's my guess.

If Nintendo don't screw up and implement the Gamepad well it might become the most important game for Wii U. Even if sales turn out to be slow in 2013, Mario Kart U will be the turning point.

Holy crap I had no idea Mario Krat Wii was at almost 33 mil! :-O

22-25 million most likely..

20m plus.

Blimey, MKWii sold that much, I'm even surprised by the amount of the DS game. Colour me shocked!!! o.0

I think it will come near the Wii mario kart sales, it depends on how much will the system sell , cuz mario kart is always in the top seller games.

it depends, they need to push the series and have something new and cool. it will sell regardless! but if dont right, it will sell better!
