The basic outline of the three day event is up on the site, still a few slots being filled but that is the basic rundown.
I would urge you to pre-register if you are thinking about coming, not just to avoid the lines and not just to have a shot at the Omegathon, but also because the Doubletree is starting to fill up - particularly for the second day. There's lot of hotels around there, it's not like you'll sleep out on the streets clutching your GameBoy in the cold, but they did extend attendees a special rate you might prefer. That's all I'm saying.
