I'm pumped for Metroid Prime 4. I hope it lives up to the trilogy.
And of course, Fire Emblem Switch. They've got to give us at least a shred of info about it at E3, right?
Also I'll probably get Luigi's Mansion 3DS even though I've finished the original countless times. I'll justify it by acknowledging that it actually belongs to my grandparents 2 hours away, so with the 3DS version I'll get to play it whenever I want. lol
