I don't want to make Shikamaru Ninja uneasy so I'll expect some neat educational things or app-like software that makes use of the gamepad rather than something "grand"
I know Miyamoto did the Louvre guide recently, for instance. And the WiiU has the PanoramaView software so maybe it'll be something that is "neat" and makes cool use of the gamepad in the same spirit? That's what I'm thinking in my head anyways.
