My prediction for Nintendo is:
Metroid Dread, or Prime successor, being made by Retro, for release in 2014
Wind Waker Reborn HD for release in October
Super Mario U for release in November
Mario Kart U for release in December
X, Smash, and Yarn Yoshi get new trailers, and vague 2014 launch windows
Zelda U probably gets a development update from Aonuma and maybe some concept art, but no game images. We won't see it again until E3 2014.
