So far, there are no games where you use a 3DS to control Wii U games.  We have crossplay features where 3DS games can interact with Wii U games (monster hunter) but no actual interactivity.

well that's the case for vita too..outside of maybe 1-2 games I think. Haven't really given it a go myself. But yea it isn't exactly a controller for the system. Move and DS are controllers for the system for sure.
