Im txgrim4 (Grim, Grimmy, Grimsta), i have been playing xboxlive for 9 years, evr since day 1 of Halo:CE til now. I love H2, that and Halo 1 are my favs. Im a Halologist when it comes to the Bungie/Halo Universe. Ive also played Marathon Series, ONI, and Myth Series. I live in Texas, Play Football, and cant wait for Halo 4!
No one knows exactly 100%, but if you look at the clues/Hints that you can find by looking a little closer, it all leads to Destiny. FOR EXAMPLE: In a few pictures of Bungie Staff, some were wearing a shirt that had a odd symbol that we HAVENT seen before (link below), meanwhile in the background of the studio, the same symbol on the walls(bottom). In ODST, a sign shows earth and the words, "Destiny Awaits You". Here is the site of nothing but hints.
