How can they do this to us?  2 years into development (not to mention a good chunk of what they didn't finish in Halo 2 will go into Halo 3), and all they show is a one minute cutscene that contains 20 seconds of kids talking in the fields?  Why!?

What they showed looked awesome, but why oh why wouldn't they show more?  For Halo 2, they showed a whole level off to the gaming world a year and a half before release.  Now we're less than a year away from Halo 3 coming out, and all we've seen are two cutscenes, and short ones at that, which reveal little.
