Planning on attending PAX this year? Well you'd better get your butt in gear; pre-registration ends tomorrow (7/31). Many areas are already sold out, and they're expecting a packed house this year, so head on over to www.pennyarcadeexpo.com and get your tickets now. Should be a pretty exciting event, with a great line-up planned.

The keynote speaker for 2008, respected screenwriter and developer Ken Levine, will kick off the festivities, including gamer-themed music concerts, an Exhibition Hall crammed full with over 70 companies, console and PC tournaments, the Omegathon competition and a wide variety of industry panels. Significant panels and presentations will include:

- History of Harmonix: THE ROCKENING

- How to Make the World Notice Your Video Game Blog

- The Mega64 'Panel! At The Expo'- The Power of Gaming Communities

- GamerDad's "Gaming With Children"

"We're definitely running into space issues this year" said Show Director Robert Khoo. "Despite adding another building for tabletop and an additional 120,000 square feet overall, our numbers right now say it's going to be pretty insane."
