S Tonight publishers and celebrities will descend on the Mandalay Bay Convention Center in Las Vegas to talk games with the country's GameStop employees. The annual GameStop eXpo has quickly become a great way for folks to leak tons of video game details to us each year. This year around the retailer-only show will give folks their hands on time with Guitar Hero: World Tour, Rock Band 2, Wii Music, Star Wars: The Force Unleashed, Spore, Call of Duty: World at War, Animal Crossing and, I'm told, a first ever chance to check out Halo Wars. All of the big publishers will be on hand as well as a gaggle of GameStop execs and an impressive line-up of celebrities including Todd McFarlane, Ozzy Osbourne, Mark McGrath, Travis Barker, Shaun White and "other surprise guests." If you're attending you know our email address, that's all I'm saying.
