Blizzard have filed a trademark that looks suspiciously like a future World of Warcraft expansion.

So far, the trademark "Warlords of Draenor" has been registered in both Australia and New Zealand separately...

The domain name warlordsofdraenor.com was also registered at the beginning of last month, further suggesting that this could be a legitimate future Blizzard game, although the fact that it was registered via GoDaddy is unusual for a corporate site.

Spurious and hoax trademarks are hardly unheard of in the games industry. Just 3 weeks ago, it emerged that much-hyped trademark registrations from Half-Life 3 and Portal 3 were fakes, whilst details of "The Dark Below" - a rather more ambiguous Blizzard trademark that was registered in August - are still yet to emerge.

However, it's certainly a convenient time for such a leak to occur. With BlizzCon kicking off this Friday in Anaheim, California, it's likely we will be hearing a whole lot more about future Blizzard projects in the next week. The developer and publisher has already announced that it will be revealing much more details about its upcoming free-to-play Heroes of the Storm on Friday, as well as discussing the future of the Warcraft franchise. Could that future involve a "Warlords of Draenor" expansion?

WoW - which will celebrate its ninth birthday later this month - has spawned four expansions to date: The Burning Crusade, Wrath of the Lich King, Cataclysm and Mists of Pandaria.

What do you think of this possible return to Outland for WoW?
