A little while ago Bungie revealed they were working on a video about the Halo 3 trailer. It is now available on their website, Bungie.net. You get to see a lot of what went into making the trailer, and the music composing. There are some things that got cut from the trailer, and new angles and views from in the trailer. And the most interesting part: Bungie says, "If you look very, very carefully, you'll see hints of things to come. Nothing too dramatic, but the fans will spot stuff, of that we're certain."
