I'm trying to think of what can match it given what we know about the nature of their conference.
Pokemon massive open world RPG with a well written plot out for Wii U this holiday, Chrono Trigger HD remake out early next year for Wii U, and... Uh... Metroid? That's Shenmue niche, right?
Oh, and Nintendo vs. Capcom to compete with Street Fighter V (and Killer Instinct, if we're being honest)
Either way, nothing like that is happening. So I'll bet on no.
