In my opinion this was one of Nintendo's best E3 presentations yet. I'm really looking forward to Zelda Wii U, Hyrule Warriors, Splatoon, and Super Smash Bros 3D/Wii U.
Pretty much everything lol. Most excited for Yoshi's Wooly World and Starfox Wii U of course, but the others look great, especially the Zelda titles. I've never played Bayonetta, but the sequel looks cool!
As for other stuff, there was a ton of stuff in the PS Vita sizzle reel I'm interested in, and we're hoping to get a PS4 at some point soon. I'm happy!
