Tickets for BlizzCon 2009 will go on sale May 16th, Blizzard announced today on the event's official site. BlizzCon 2009 will be held on August 21st and 22nd in Anaheim, California, and the first block of tickets going on sale on May 16th will sell for $125 each through the official BlizzCon site. A second block of tickets will be sold beginning Saturday, May 30th.
Blizzard has made upgrades to the Blizzard Store to deal with the impending ticket rush. Their press release states they'll have a "first-come, first-served queue system and a fixed time limit for completing purchases. Also, those interested in attending BlizzCon can simplify the purchase process by registering a Battle.net account at www.battle.net before ticket sales begin."
For those Blizzard fans unable to attend BlizzCon in person this year, DIRECTV will have a BlizzCon Pay Per View event for $39.95, with a minimum of eight hours of live HD coverage each day of the event, including interviews and demos. The BlizzCon 2009 pay-per-view event will also be the first time it's been made available as an Internet stream (same $39.95 pricing), which will be free to DIRECTV customers who've ordered the event. Ordering the event will give players a BlizzCon-exclusive in-game item, the details of which have not yet been revealed.
This is the gist of the announcement, but you can check out the Blizzard press release for further details on BlizzCon 2009.
