The video streaming as a test on the page suggests that both Level 80 Tauren Chieftain will be playing and Jay Mohr will be hosting again, though that video is likely from last year, and not necessarily indicative of this year's show. It looks like the HQ stream will also require you to install the RayV player, while the lower quality stream will likely be available just through Flash. You can also keep in mind that though this is probably an excellent deal (especially if you want that pet -- I know many people will pick up the package for that code alone), there will be no shortage of information from BlizzCon for sure, as we'll have plenty to go around as well. But if you were planning on picking up the Internet stream, order on up.
