Zelda is really looking amazing. I love the lighting and of course the gameplay will be the best part. Re4 looks even better though everything looks so real and they dont even use cutescenes, it looks THAT good. Viewtiful joe was fun so I will naturally be buying the 2nd one. And Ill be buying a DS when it first comes out.

Halo2 will be really good too.

Nintendo owned e3.

EDIT: Also pikmin 2, the first was fun and 2player will make it better.
