Apparently titled "Halo: Reach". Bungie started a forum for it, but quickly took it down, but alas, nothing that happens on the internet can be undone.

Any thoughts? Personally I hope this is the game by the new studio MS put together(with the Gearbox, Bungie, and Kojima vets), and that it will release sometime in 2010, filling out the obligitory blockbuster holiday FPS, thus giving Epic another year for Gears 3(so it wont blow cock like 2). All and all, this could be the Halo game we've wanted since Halo 2, and Bungie has refused to give.
