I can honestly say that there's no more updating on the progress of the game, since the game is done. Finished and shipped to a nebulous region known as RTC (Release To Certification) where it will be dumped from eight digital tapes onto a DVD and go through some final testing. Usually that's just a matter of routine, but we'll be watching our email carefully through next week
Next week's update will be kinda special, so keep an eye out for it, and in the meantime, we'll keep you posted with every granular detail of what to expect from Halo 2.
