Blizzard Entertainment revealed today that its gaming hit 'World of Warcraft: Mists of Pandaria' will be released on September 25, 2012.

The upcoming September release will make this the fourth expansion of the gaming system.

The game will come out in three different versions. The standard edition will cost $39.99 and can be bought from Blizzard Directly or purchased in retail stores. The 'Digital Deluxe Edition' will run customers for $59.99 and the Collector's Edition, which can only be purchased in stores, will go for $79.99.

The difference between the 'Digital Deluxe' edition and the Collector's Edition is that the Collector's Edition provides physical assets. Otherwise, both versions have all the same game bonuses.

Blizzard issued a statement about its upcoming expansion pack saying: "Mists of Pandaria contains the biggest variety of new content we've ever created for a World of Warcraft expansion, with features that will appeal to new players, veterans, and everyone in between," said Mike Morhaime, CEO and cofounder of Blizzard Entertainment. "We've received a lot of great feedback from players during our most extensive beta test yet, and we hope they enjoy exploring everything Pandaria has to offer when the expansion comes out in September."
