Did you know Best Buy has forums? Well they do, and they're hosting a live World of Warcraft developer chat today. Here are the details straight from Blizzard:
"If you're looking for the latest Cataclysm updates, be sure to join World of Warcraft Production Director J. Allen Brack and Game Director Tom Chilton as they field questions live online today, November 18 from 4 to 5 p.m. PST. The chat will be hosted and moderated by our friends over at Best Buy, so be sure to visit their forums for all the details. Participation is limited to the first 500 attendees, so be sure to arrive early if you'd like to submit a question to the developers. If you can't make it into the chat, Best Buy will provide a Ustream mirror here."
Zarhym mentions in the comments section that Blizzard has plans to post the answers online, so keep an eye out for them if you can't attend.
