I think you guys got the wrong idea about the Wii U.
the Wii U is backwards compatible with Wii games so you can use the Wii Remote/Nunchuk. the most they will ask you to do is tilt the thing or touch the screen. if you don't buy the Wii U Pro Controller on day one your doing it wrong..
they already got third party Super Famicom Wii U Pro controller
