The interesting part is Aussie-Gamer's hint. Something to do with "multiple dimensions".
Obvious possibilities include something to do with Portal, Dead of Alive: Dimensions (3DS game - could perhaps be being remade on Wii U), or that Oliver and Spike game that has the three dimensions, which is already confirmed as being developed for Wii U (among other systems).
