Check out id CEO Todd Hollenshead's . dot plan for some infos on Quakecon (where some game is being demoed... I forget the name of it at the moment):
The BYOC will be the biggest yet, with room for up to 2000 PCs. The reservation list is booked up, but first-come-first-serve starts Thursday afternoon if you didn't get on the list. The keynote is Friday afternoon, and tournament finals, awards ceremony and party are all Saturday night. But the fragging is non-stop Thursday to Sunday 24 hours a day.
