The event is scheduled to start at around 1:25PM ET / 10:25 PT.[9:48AM PT] We're lined up outside USC's Galen Center, mingling with the rest of the riff-raff (read: media), being herded through a labyrinth of stanchions and fences. Hey, remember that "very special addition"? A PR person just walked into the crowd and called for anyone from "Apple, MTV, or EMI?" So, a Beatles appearance then?Filed under: Gaming
