More informations makes itself known for the Penny Arcade Expo (PAX) for this year, as we disclose details for the event's Omegathon competition, keynote speaker, and headliner band.

For the pre-registrants of Penny Arcade's upcoming PAX 2007 event, we imagine one thing you'll be looking forward to (or dread) is the Omegathon event. This yearly PAX event pits 20 randomly chosen "Omeganauts" from the pre-registered crowd in multiple bouts of tabletop, videogame and computer game matches, culminating in a final match conducted onstage in front of PAX's thousands of (expected) attendees.

This year's Omegathon grand price is a trip for two to the Tokyo Game Show (September 22 to 23), plus US$ 5,000 in travel money. Not exactly a new truck, but given the price of gas these days, we like it.

On the matter of PAX's keynote speaker, the organizers have managed to pick up Wil Wheaton - trekkies will remember him as Wesley Crusher from Star Trek: The Next Generation. Outside his acting role, Wheaton has also authored two books: Dancing Barefoot, and Just a Geek.

As for tunes, PAX 2007 is expected to dance to the tunes of The Minibosses - gamers will this band for its rock revisions of  the music of classic titles  like Mega Man, Metroid, and Castlevania. Other musical guests expected to make it to the event are The OneUps, MC Frontalot, Jonathan Coulton, Freezepop, The Neskimos and Optimus Rhyme.

This year's PAX will be held from Aug. 24 to 26, at the Washington State Trade and Convention Center in Seattle. Ticket prices for both pre-registration and on-site registration should be available at Penny Arcade's PAX site (read link).
