BlizzCon will be hosting a voice actor stage with several panels over both days. Many of the voice actors from World of Warcraft, Diablo and Starcraft will be on hand to discuss their craft as well as sign autographs. Posters will be handed out to be autographed during the sessions in between the panels.
Included on the Warcraft panel Friday between 3 and 4 p.m. PST will be the voices behind Chen Stormstout, Garrosh Hellscream, Jaina Proudmore and a few others. To see the schedule and all of the voice actors appearing, go to the original post.
The stage will be setup between Hall A and B and is described as being attendee-only, so those watching on the Virtual Ticket will be out of luck.
