BlizzCon is one of the biggest single developer conferences out there and the huge amount of Blizzard fans made the company host two events in a single year. The first one, the Blizzard World Wide Invitational, was more for the press, with the much awaited announcement of the Diablo III title. But now, the developer, which has recently merged with Activision, will start the BlizzCon on Friday.

Held in Anaheim, California, at the Anaheim Convention Center, BlizzCon will be a massive scale event that promises to give the dedicated fans playable versions of upcoming titles, like World of Warcraft: Wrath of the Lich King, Starcraft II or Diablo III. The convention is already sold out and the organizers are preparing for the massive number of fans that will invade the center this weekend.

"With more hall space, more attendees, and more attractions, this BlizzCon will be our biggest yet," said Mike Morhaime, CEO and cofounder of Blizzard Entertainment. "We’re working hard with our partners to make this an unforgettable experience, and we’re looking forward to meeting players at the show."

The event will continue to unfold until Saturday evening when it will end with a performance by comedian Patton Oswalt. Also making special appearances are Blizzard's own metal band based on World of Warcraft, Level 80 Elite Tauren Chieftain and the very popular Video Games Live Orchestra which will be playing theme music from the most well known games created by the developer. Also, during the whole event, attendees will get to speak with special people from the company regarding the development process of their upcoming games.

As a special feature for those of you who can't make it to the show, Blizzard will be offering special coverage on the convention's site. Also, all those who might be interested in working for Blizzard can bring their resumes to the convention, as special employees of the company will be there to evaluate their skills.
