Halo 3 Recon

The official title of the expansion, which will be a prequel to Halo 3, is Halo 3: Recon. Kinda generic but a title like Halo 3: Watch Out, The Covenant Is Here would've been too on-the-nose. The expansion is due in Fall 2009, apparently, meaning that the earlier rumor that it would arrive this January was false. That's a long time to wait, but it does indicate that this could be a pretty sizable expansion.
