Joystiq mentioned earlier this week that two-time Slashdot interview subject Wil Wheaton, world-famous blogger and writer, is scheduled to keynote this year's Penny Arcade Expo. Other headlining elements of this year's geekstravaganza include a Tokyo Games Show trip for the Omegathon winner, and another year of the 'face-melting' Minibosses as the big musical act of the event. From Gabe's Post: "We'll actually be taking a lot of steps this year to make the Omegathon a more important and interactive part of the show experience. I can't say much more about those ideas right now but I can tell you what this year's Omegathon prize will be. I think each year we've been able to out do the previous year's prize and this year is no exception. The winner of the 2007 Omegathon will receive a trip for two to the Tokyo Game Show along with $5,000 in spending money. We'll be taking care of everything for you from airfare to hotel and giving you some cash to spread around once you get there."
