I think 3D screen is out next gen.
They could keep some of the same Wii U controller concepts as an optional thing next gen.
If you own say the Nintendo Fusion handheld and Fusion microconsole ... there's probably no reason why they couldn't allow for things like being able to use the handheld as a controller for the console if you want and display things like inventory and maps on the screen or use it as a touch interface to do things like create levels (ie: Mario Maker).
