Bungie, on their self-proclaimed "Bungie Day" (yawn) released some cool Quicktime movies (although they're not really movies) detailing some 3D views of two new Spartan types. In them they're hauling around some of the new, heavy weaponry and you can also see some of the new armor that will supposedly be able to be used in Halo 3 multiplayer (helmets and arm/shoulder plates).

There are also some movies and specs/lore on a Brute Chopper on the page.
