That story is very missleading. They did have some huge A/V issues but the online worked just fine. The guy demonstrating just played poorly which made it so that you never got to see the two human players on screen at once.
I watched the presentation live at work (streaming) and I was LoL at the dude\'s playing the games. They all were lousy.
The guy playing Halo was trying to show some features, and was like "I hope I don\'t die, they\'ll fire me." as a joke. 10 seconds later, he died.
My little sister could drive a car better then the dude who was driving in NASCAR.
It\'s like these guys have never played the game before. You\'d think they\'d put in at least a couple of hours practice before demonstrating the game.
