Blizzard Trademarks "Mists of Pandaria", Next WoW Expansion?

MMO-Champion spotted a new trademark filed by Blizzard for a mysterious "Mists of Pandaria", which they speculate could be the title of the next World of Warcraft expansion, since, according to the website, the international codes match with the developer's past online trademarks.

If the folks at MMO-Champion are onto something, we can probably expect an announcement at this year's BlizzCon, which will be held from October 21-22.
