The 2008 Penny Arcade Expo Omegathon V lineup has been revealed and it feels surprisingly casual. There's no Doom or Quake title like we've seen in every previous Omegathon. Also new: starting the first round with a non-board game (Jenga has been pushed to round 5). Here's the list:

• Round 1: Peggle
  
• Round 2: Boom Blox
• Round 3: Pictionary
• Round 4: Rock Band (Our guess is Rock Band 2)
  
• Round 5: Jenga
  
• Final Round: *** TOP SECRET ***
  

The 20 Omeganauts have already been chosen (congratulations to any Joystiq readers who made the cut!); first prize this year is a trip for two to the Tokyo Game Show with all expenses paid and $5,000 in "walking around money."

While last year's Omegathon skipped the previous tradition of using a classic retro title (Pong, Combat, Tengen Tetris), every year has featured an id Software shooter. With Rage, Doom 4 and the new Wolfenstein looking unlikely, we're trying to think of another potential, unreleased FPS that could top last year's surprise Halo 3 inclusion. If Tycho and Gabe are looking to make our heads explode, maybe they can get Duke Nukem Forever. We won't find out until minutes before the final round on Sunday, August 31 at 4:30 PM PT.
