Yes it can provided 3DS gets a way to go online for the hunts and/or Nintendo gets awake and makes something to promote the Wii U more.

The game in itself is pretty solid and I'm charmed anew for the series. :]

Between PS Vita launches and HQ Sellouts that's the only thing they can really do. I wouldn't pay much attention to it.

Still... would not complain if they added some new tracks to the 3DS library.
(and maybe an update with the new characters. xD)
