Disgaea 6 obviously.
Bonus: Hmm, I don't know. If the rumours are true and Nintendo shows a Switch Pro, then I think they also have to show some big games to accompany the new hardware. Zelda and Metroid would be obvious candidates. That would indeed be interesting. If the rumours are wrong though, probably nothing earth shattering happens at E3.
