-3D Mario/Mario Kart/Smash will be at E3 (shock)
-Virtual Console coming to Wii U, reduced prices on games you already bought on Wii (still ugh, I'll just keep my Wii)
-New Yoshi game; 2D, looks identical to Kirby's Epic Yarn
-New Monolithsoft game; looks like Xenoblade with obvious graphical upgrade and some sort of multiplayer. Insane scale, mechs.
-Fire Emblem crossing over with Shin Megami Tensei (not Persona)
-Wind Waker HD this year, looks weird
-Miiverse/OS updates forthcoming
And, most importantly of all, Kamiya is back. I don't give a fuck what you think about Nintendo's games, but if you aren't interested in what Platinum are bringing, I don't want to know you.
