10:00 a.m. PDT tomorrow.
As we've mentioned before, BlizzCon tickets this year will be handed out in a queue system. That means first come first served. If you haven't done so already, follow our pro tip and get your Battle.net account setup today.
We'll be here with updates throughout the day tomorrow on the ticket sales, and hopefully it will all be smooth. However in the event that sales falter again like they did last year, expect to see that news as well.
