Here's some more information that may or may not assuage the rage if you weren't one of the lucky few who fought past the Fail Murloc to get a BlizzCon ticket. DIRECTV subscribers will have the chance to get the BlizzCon bear mount.
DIRECTV will be selling a BlizzCon coverage package directly through the official BlizzCon site. This package will be free to any new DIRECTV subscribers who sign up through the site, and cost $39.95 for anyone who's already a DIRECTV subscriber.
By purchasing the package, you'll not only get 16 hours of BlizzCon coverage, you'll also get the aforementioned BlizzCon bear mount, the same one that all the con attendees will get in their goodie bag. Sounds like a pretty good incentive to me. The package isn't available for purchase yet, but keep watching the official BlizzCon website to find out when it will be.
