Microsoft is planning to release the Halo 2 E3 trailer, which showcases American journalists "wooping" and "hollering" uncontrollably in an orgy of discarded integrity, as a high resolution video with 5.1 surround sound this Friday. At 10:00am PDT. We don't really know when that is, but it's probably just after you go home from work.
Apparently, Bungie's website will also be updated in the coming days with new Halo 2 content including a behind-the-scenes look at the E3 demonstration.
You can already download the Halo 2 E3 trailer in various "shaky cam" guises, as Bungie puts it, including one from FilePlanet. It's also on various BitTorrent sites as a much larger file, if you know what that means, and all the usual file-sharing applications probably have it too.
You can read what Kristan made of the trailer when he saw it at E3 here.
As you will no doubt recall, Halo 2 is due out in early 2004.
