Come on, Nintendo.
You really didn't reveal anything new regarding Metroid Prime: Federation Force or any info about the series itself at E3 this year? I know a lot of people have mixed opinions on Federation Force at the moment, but I still think you could've at least had a demo of the game at E3, or maybe just talked about it and/or revealed a couple new things about it. Because from what I've read and seen so far about the conference, neither was done for the game.
I bet some minds could've been changed about Federation Force if it would've been shown there at E3. Guess now we'll never know.
