This week you should set your sight on the official Blizzard websites for an imminent official announcement of the BlizzCast. The first episode is an audio podcast featuring an interview with Samwise Didier, Senior Art Director at Blizzard who will share details of the Art Direction of Starcraft 2; and Jeff Kaplan (World of Warcraft Developer) who will unveil details of the Sunwell Plateau (patch 2.4). A transcript will be made available by Blizzard Entertainment in each supported language. Tell your friends online, at work, at school or at forums.
An official date wasn’t given to me, but things are in motion now that everyone is back from the holidays.
Update(1-03): BlizzCast has been scheduled for early next week. I will keep you informed as info comes. Blizzard is very excited with this new community project.
