Soe, Xenophics, and Arx will be taking a trip down memory lane, talking about their favorite moments from WoW's past and how the game has evolved over the years up until patch 5.4. They'll also be discussing what the future has in store with Warlords of Draenor and its new features. There promises to be in-game events to participate in, but the details of what realm this will happen on won't be revealed until during the event. Since this is a EU based event, you can assume it will be on EU realms only. You can also participate through Twitch.tv for a chance to win prizes. Further details are available here.
