Oordinarily I'd say no way, but with the surprise showing at TGA, I guess anything could happen. I really don't expect to see anything more on Zelda till E3, though. As some have speculated, maybe a tease or mention but no new footage.
The Lobby, Gamespot's Live show are talking about Zelda U tomorrow on the show. Oddly specific, and with the timing..
Tomorrow on The Lobby we talk Zelda Wii U, the best & worst Resident Evil plus the games available on PlayStation Now
I'm not saying anything will happen, and nor should there be any expectations, but the timing could be more than a coincidence.
