It makes sense for the Wii U, which can run the bottom screen on the controller's touch screen. I wouldn't be surprised if we saw that.

However, due to the limitations of wireless devices, the Wii U cannot broadcast to the 3DS and another wireless network at the same time, so it would probably not have online... Unless the Wii U only accesses the 3DS to access the game cart (maybe an optional game cart slot) and save.
