Hockey, for sure. Just isn't the same as a replay, whereas game news can be good as a replay. Easy choice for me, though I'd love to see the E3 stuff live.
Microsoft's announcements sounded awesome, but I really want to see the Nintendo is bringing with their new console, but I'm at school tomorrow when they show it off.
I watch E3 Live on GTTV (gametrailers, not G4). Looked awesome, glad to see they are doing more with Kinect than just dance and kids games. The new Tomb Raider game looked promising as did Fable.
