Blizzard has today announced that their next expansion in the mammoth of an MMO World of Warcraft is now available for pre-purchasing, with the standard edition available at $54.95 and the digital collector's edition at $74.95. Both versions include the free level 90 boost, which can be used ahead of the expansions launch.

“We’re sending players deep into uncharted territory with Warlords of Draenor,” said Mike Morhaime, CEO and cofounder of Blizzard Entertainment. “New features like the Garrison will give players a commanding role in the Warcraft saga like never before, and everyone can get in on the action right away with the included level-90 boost. There’s never been a better time to go to war for the Horde or the Alliance.”

Australian goers will also be welcomed by the new AUD currency support, which is now available across all Blizzard products including World of Warcraft's micro-transactions.

Blizzard has yet to announce a solid release date for the fifth expansion, though according to the pre-order page you can expect Warlords of Draenor out sometime during Spring 2014. Those who go through with their purchase are being greeted by a promised release date of before 20/12/2014. Previous World of Warcraft expansions have seen a release date sometime during the September - November period.

The fifth expansion to Blizzard Entertainment’s acclaimed massively multiplayer online role-playing game leads players to the untamed world of Draenor, where the orc warchief Grommash Hellscream is forging his twisted Iron Horde into a world-shattering weapon of conquest. Faced with seemingly insurmountable odds, the champions of the Horde and the Alliance must establish a base of operations on Draenor and seek out courageous allies to make a stand against Hellscream’s mighty war machine.
