Seeing as how I'm actually able to, and WILL be going to E3 this year, I'd say it's probably, no, easily the most exciting one I've been anticipating.
I remember really getting really excited about the GameCube just from the information I was finding on the 'net. Those E3 videos were awesome. An E3 before a new system launch is going to have a lot of hype, so of course those are the hard ones to top. With next-to-nothing seen of actual Revolution games (other than some fuzzy scans of Red Steel), we can probably expect to see a lot of them at E3, so it's more exciting than any old year with a few plain old new games. (If that makes sense.
) New system! New control scheme! (No booth babes? Not an issue!)
But, again, I'm actually going, so HA!</immature gloat> Unfortunately I probably won't have much of a chance to be online at all until I get home. so by the time I write up anything, everyone will be tired of all the other hands-on impressions of the Revolution on the Internet.
