Well it look like the release date is official read for yourself.
Release date from bungie.net
But they also released the first ever halo 2 mutiplayer screenshot and a bit of news. But the release date really brings me down,oh well more time means a greater game
also here's the mutiplayer picture but i noticed something in the way back of the picture. it was almost unnoticeable but i circled it with some red ink on a paint program.

that looks in the back to either be another player but another feeling it looks like a flood to me. probaly not but i just noticed that by looking around on the picture.
