Will the NX be compatible with all the controllers, from GC to WiiU?

Compatible from NES controllers. I want a classic type controller (maybe a WiiU Pro controller) with a touch of GCN controller. but all previous controllers can be used. Hope they can find a way to have that motion like on the Wii / Wii U but doesn't need that sensor bar. or sell it as optional for those people who wanted backward compatibility on previous controllers and games.
