Does it look like multiplayer (with just one wiiU) will be a possibility?

I'm just asking because the alternative means me and my brother buying two WiiUs to play online. Kinda gross. Anyways yeah, does it look like they'll be able to implement that sort of multiplayer, that is to say two people could use one console, and be able to play online? I mean if I remember correctly it did work on the multiplayer arena in Tri, I think the WiiU could handle it.

EDIT: just noticed another thread about, you know, multiplayer. (Thought not specifically about this. Right after looking for a questions thread.) Feel free to lock this. I think i know the answer to my question.

Locking the thread per OP's request.
