We want your HALO 3 screenshots here. Add yours.
The Hushed Casket was founded in 2002 shortly after the launch of the XBOX console. Today the Hushed Casket is a thriving community of gamers, playing together and publishing news and stories that have appeared in major media properties like Newsweek, G4TV, USA Today, and Penny Arcade. Some game developers have even referenced our guides and news to support their gamers. We don't play Halo. We LAN Halo.

I haven't said anything for a day, so..
Some of the theories people have said are just way to far off of the storyline to work , but I've thought about a lot of them.
I think that it's obvious that Humans are definintely related to the Forerunners, since Bungie has been trying to push that since Halo. I also like the idea that there be more than one spieces in the Forerunner grouping. If you think about it Guilty Spark and Penitent Tangent (the red one with Gravemind) never call Humans Forerunners, just Reclaimers. I wouldn't be surprised if the Elites were once involved somehow with the Forerunners. And its kind of a given that Humans and Elites will eventually work together, if not in the beginning of Halo 3. That would explain why the Arbiter and his Elites didn't just kill Keyes and Johnson.
Also, I think we have as much info as we can get so far. MS probably has to make the next move. The only question is when.
