BlizzCast episode 16 is a little different from what we've come to expect from the BlizzCast. It isn't an audio podcast. It's video! A vodcast, if you will. In the first-ever video BlizzCast, Blizzard's Rob Simpson speaks with Game Director Tom Chilton, Lead Quest Designer Dave Kosak, and Lead Content Designer Cory Stockton on the content of patch 4.2, from the raid to the quests and back again.
You can watch it embedded above, over on YouTube, on the Battle.net BlizzCast site, or if you're a little more old-fashioned, you can still download it in MP3 form on Battle.net.
