Rumor: World of Warcraft's next expansion has been named

First there was The Burning Crusade, then Wrath of the Lich King, and, most recently, Cataclysm. World of Warcraft's expansions have been the lifeblood of literally millions of gamers' playtime, which is why many fans are anxiously awaiting word of the fourth expansion pack to the hit MMO.

Today we may know the name of the expansion: Mists of Pandaria. According to MMO Champion, Blizzard filed a trademark with this title on July 28th, which is exactly in line with how the company has procured titles for the previous expansions. The trademark specifies that this is for "computer game software."

The Pandarens are one of the more light-hearted races in the Warcraft franchise, with kung fu panda bears from a secret empire somewhere in Azeroth. Despite being fan favorites, the Pandarens have been rarely seen in WoW, while Blizzard has used them in a couple different April Fool's jokes in the past.

We'll be keeping our eyes on Blizzard for any official confirmation.
