The podcast kicks off with their usual Q&A portion. The World of Warcraft questions, answered by Tom Chilton, were aimed at Wintergrasp and the vehicle system (specifically the lack of aerial combat). That's the full extent of the WoW content here. That's all, folks. If WoW is all you care about, that's the end. For those of you that are Blizzard fans in general? Jay Wilson (Diablo III Game Director) and Dustin Browser (Starcraft II Lead Designer) cover the Q&A for their respective games.
The remainder of the podcast is a Diablo III interview with a pair of the game's developers, Julian Love (Lead Technical Artist) and Mike Nicholson (Senior Artist). If you intend to play Diablo III, it's worth a listen. It gives some insight into the developmental process of the game, and that's probably the most interesting part of these podcasts.
