It could just simply be one of the tools Link can use like the bow and arrow.

Nintendo can't gamble with the controller three times in a row. They hit the jackpot with the wiimotes, they lost with the gamepad, and with this magnet-controller, it's just going to make Nintendo look sillier. If this one is true, blease be an optional peripheral.

And so it begins.

Looks legit, could be used as a steering wheel considering the shape.

I thought it was just a magnetic item Link gets to move stuff around.. really hope that isn't the NX controller

It also looks like a DS oriented screen can fit right in.

Link has a GamePad. I doubt the NX version is going to look radically different than a smaller, more optimized GamePad.
