I actually think the new Zelda, Epic Mickey, and Donkey Kong are going to be great. Just a little disappointed they didn't go with the hyper-sytlized toon shading for Zelda though.
The new Metroid doesn't really interest me. Probably because the only Metroid games I've finished are the Prime ones.
I'm cautious but optimistic about the 3DS. The elephant in the room is that that type of 3D only works within a certain distance and a certain angle so that could be very bad for a handheld device. There's no way I'm going to buy one until I try one in a store, but the design of the 3DS looks great (finally an analog stick) and the actual way that you use motion to tilt around in 3D seems a million times better as far as game design than the way 3D could work on a fixed TV or monitor for PC and console games
