Finally! We have the official announcement now!
This year's band performing at BlizzCon will be Blink-182. After bands like Tenacious D or Ozzy Osborne it's time for the legendary punkers from Blink-182 to entertain us in the closing ceremony of this great yearly event.
Even if you are not present at the event you'll be able to see their performance by buying a BlizzCon 2013 Virtual Ticket.
