• While Blizzard has finished the main recording, the company is still fine tuning things and thus cannot give an ETA at this time.
  
• Blizzard is still keeping a lid on the new interviewees for Blizzcast 2
• Blizzcast is not a weekly production. Blizzard doesn't have an official timeline as to when each and every broadcast is supposed to come out.

And to build off what was said, the tag line at the top of the official BlizzCast page is "Taking you deeper into the world of Blizzard." While new game/content information might be discussed from time to time, that isn't the primary goal.

Instead we want to bring some unique perspectives to the variety of aspects involved in making games and our company in general.
