I can already see this coming --
Standard GP for classic Mario Kart
And a "new" Double Dash style mode, with dual-racer karts. One player steers with Wiimote, the other player in the back has the Wii U tablet and mans a "weapon turrent" and has to spin around and use the Wii U tablet's gyros to see other racers/obstacles come from all angles and shoot them away. Could also hit speed boosts this way. Stuff like that.
