BlizzCon sold out extremely fast, even though the site experienced technical difficulties on its initial ticket sale day. Many Blizzard fans who were hoping to attend the convention wept, but CEO Mike Morhaime apologized on the whole situation with a post on the World of Warcraft forums. He stated:
"Due to these circumstances, we've reevaluated our convention hall space and come up with some solutions that will allow us to offer 3,000 more tickets for sale. We know this will not be enough to satisfy the very high level of demand for tickets this year, but we want to ensure that BlizzCon remains a great experience for those of you who are able to attend. To avoid the issues many of you faced this week, we'll be selling these 3,000 via a lottery. We'll post further details once our plans are finalized. Please note that the lottery will only be open to those with an active Blizzard Account as of 9:00 PM PDT on August 12, the time that the “Sold Out” notice was posted."
So there you have it. But for those who do not meet the requirements of the ticket lottery, there's always plenty available on eBay...for about three times the original price. That's a lot of farming. BlizzCon will be held at the Anaheim Convention Center this October 10-11.
