Legend of Zelda: Skyward Sword - 1:1 control of Link will be so much fun, definitely looking forward to this.
Donkey Kong Country Returns - The first on the SNES was one of my all time favorite games, absolutely LOVED it (just wish it was harder). So much fun and the graphics had a great feel to them. I was not expecting this announcement, and am immensely looking forward to this game.
Metroid: Other M - This looks like it will be a blast. The Prime series was fun, but I am looking forward to the more traditional style Metroid. Not sure about the whole deal with Samus' background, but the fighting looks great and the exploring in Metroid games is always fun.
Kirby's Epic Yarn - Kirby games are almost always amusing, and I like that they're reinventing them some as they go. This premise behind this idea should have a lot of potential for ways to interact with the environment, and based on the video it looks like they'll definitely be taking good advantage of this.
GoldenEye 007 - Normally not into FPS too much, but GoldenEye was such a classic that I'm very interested in this, will be fun to do more multiplayer GoldenEye

.
3DS - Really, I have no idea about this. From the sound of it things could go either way. I want to try one out in the store before I'm sure if I'll buy anything for it.
