Not sure if there is already a topic for this, but I searched and nothing, so here we are. 
Personally, I have no idea how Mario Kart could work better in 3D.
But, I can see the kart being in full 3D popping out of the screen, and then when you drift around a corner, the kart slips into the screen. And with the turbo boost, you zoom staright into the screen into the distance before suddenly slowing down and slipping back out of the screen. 
So... how do you think MK3DS will take advantage of the 3D aspect?
