since they could not come up with anything cooler than the gamepad, they could enhance and support the already popular Wii controls, for example:
- wireless Nunchuck-plus to work with the Motion-plus and then a new deeper Wii Sports U taking advantage of the Nunchuk-plus, more customizing and more sports
- an improved Balance-Board plus? with better sensros and jumping to work well with a Wii Fit U 2 or smth, instead of a last-gen hardware most people have already used over and over
I believe these would work better for many 3rd party games than the gamepad, for example Watchdogs and Assassin's Creed would even work in a cool way with Nunchuck and Motion plus
some games like Pikmin 3 support the Wii remote and nunchuck, so would an improved WiiU version of the Wii controllers be a good idea?
