Most importantly Wii u pro controller, but possibly game pad (switch is perfectly capable of diliverying data to gamepad) and wii motes as generic controllers (Nintendo might charge for receiver adapter and resell receiver for wii game support as wii is barely faster than game cube).

They are not out of the picture. And with some add-on the joycons can become next gen vr controller that double as superior wii motes.
