The Xbox 360 Launch event will take place at a yet-unnamed location in the middle of the desert in CA. There will be thousands of gamers there from around the world, celebrating the launch of Xbox 360. There will be copious Xbox 360 systems set up with high-def monitors, surround sound, the works. Plus food and drink stations, live entertainment and a one-of-a kind Xbox 360 gift for everyone. Microsoft is calling it “Burning Man Meets E3″– it’ll be a party unlike anyone’s ever been to.
I’ll bet. More details by following the link.
