Dragon's Crown for the PSV was the only thing that caught my eye in the e3 coverage. Sadly there wasn't anything really said about it, and it was a surprise that was only shown for like a couple seconds in the Vita promo footage.
The Wii U isn't really anything exciting to me, it's basically just an upgraded Wii from what I've seen with this additional controller. To me it's like they've upscaled the DS to use in your living room, having you use two screens and a touch screen to play. I wouldn't be surprised if they announce it'll come bundled with 3D glasses. Also the design bothers me, the controller looks like one of those play&learn devices, and the Wii didn't receive a re-design, they just knocked it over on it's side.
