Source - Blizzard

You can now Pre-Order Mists of Pandaria, which will be out September 25.


 By pre-purchasing the game digitally. Plus, for the first time ever, players will have the option to upgrade a pre-purchase to the all-new Digital Deluxe Edition which comes with all of the in-game items from the retail Collector’s Edition, including a World of Warcraft pet and mount, banner sigil and accent for Diablo III, and Battle.net portraits for StarCraft II.

Beginning September 25, 2012, World of Warcraft players around the world will be able to set sail for the long-lost continent of Pandaria, where they’ll explore forgotten dungeons, vanquish risen evils, and play their part in the Horde-Alliance conflict as it reaches a critical breaking point.
Whether you plan to level your existing character to 90 or start fresh with a new pandaren monk, it’s never too early to begin preparing for your adventure. Simply log in to your Battle.net account, and then pre-purchase Mists of Pandaria. You’ll then be flagged to automatically download the expansion content prior to release so you’ll be ready to go when the game launches.

During the pre-purchase process, you’ll have the option to grab either the Mists of Pandaria Standard Edition for $39.99 or the all-new Digital Deluxe edition for $59.99 -- or, if you snag the standard edition now and decide you want to upgrade to Digital Deluxe later, you’ll have the opportunity to do so for an additional $20.

The Digital Deluxe edition includes a full digital copy of the expansion, as well as a selection of Pandaria-inspired in-game content for World of Warcraft, Diablo III, and StarCraft II. If you’re looking for even more plunder, a special Mists of Pandaria Collector’s Edition with additional bonus items will also be available exclusively at select retail locations for a suggested retail price of $79.99 .
