Blizzard announces Metallica will perform the closing concert at this year's BlizzCon, presuming the heavy metal band doesn't fire their agent when they learn of the booking. The show gets underway on November 7th and the concert will follow on the 8th, but tickets all sold out pretty much immediately, so those interested in seeing this will have to opt for a BlizzCon Virtual Ticket (admit it, you thought we were going to say Napster). Here's word: "BlizzCon is a gaming convention like no other. With developer panels, exclusive interviews, intense eSports tournaments, the legendary Friday night contests, and what’s sure to be an unforgettable concert from Metallica to close out the show on Saturday, this year’s event is one you won’t want to miss."
