Here is a free live feed of the Diablo 3 Lore panel which is broadcasting 10:00-11:00 PST (18:00-19:00 GMT). You need to register but I tested it out and it was very easy and just click this link below for the feed. Here is another at Twitch.TV which doesn’t require registration. Thanks to Gadwin and jamesl for the feed links. Keep an eye on our live chat room for more feeds.
I encourage you to watch this – there are new areas on display and gameplay in them.
