The company revealed Mario, Pikachu and Zelda-themed controllers on Tuesday, which connect to the Switch via USB and have extra buttons that account for the ZL, Home, + and - buttons that aren't on the standard GameCube controller. A programmable button is also on the controller.

The main cons to the controller are that it's wired and won't have motion controls, HD rumble, an IR sensor or NFC.
