What Wii/WiiU add-ons/peripherals will work on the NX?

[V-r0cK]

I feel that it'll be all new, but the only thing that'd make sense to me that would work still is the Wii U pro controller for when playing the NX on your TV. But that's also if Nintendo choose to keep the same format of controller/buttons for the NX (ie. no Touch pad/screen required etc..)
