In addition to repeating their intention of releasing a Win2K Anachronox patch tomorrow, Jake Hughes' .plan has word that ION Storm is also shooting to get the demo released tomorrow, as well:

Anachronox is on the shelves. The trailer is up. There are now some mirrors so the download isn't so darn slow.

Programmers are solving the win2k probs with the patch that should be out friday hopefully. While the rest of us are putting together the demo. Which we are trying to have ready by tomorrow as well. We'll see Mr. Frodo... We'll see.

Update: As noted in Brian Eiserloh's .plan update, the Win2K bug has been tracked down and squashed, and since it affects other operating systems as well, "users of ALL OSes should download the 1.01 patch when it becomes available (probably no sooner than friday night)."
