Track creator? Come on, all the cool karting games have one.

i bet they go with Mario Kart 8.

20+ million confirmed! who doesn't want a wheel of the Wiiugamepad!

As long as Mario Kart Wii U supports Pro Controller, I do not care what they do with the GamePad.

while kind of cool as an idea, the dependance on actually having two players seems limiting. what if you only have one player...you only get to drive?  sounds like a huge disadvantage.  

and if i have to spin a full 360 to see everything... i would not enjoy the game.  too much effort to be fun.

You know how when you collect an item, you get the little slot machine display that reveals what it is. You could have that on the gamepad and the player could tap it to try and stop it on the item they want. (If left alone, it will stop automatically after a few seconds as normal).

This could create a nice little risk reward mechanic, since the player would have to take their eyes off of the main screen to attempt it.

I want to see behind me. Maybe have an item that lets you see way ahead of the player for a short time. This way you can see up coming danger.

The Pad seems to have really good motion sensors... motion control might...MIGHT.. be fun using it.
