As you might remember, last month we reported that Blizzard trademarked the title "Cataclysm," which led to speculation that the next World of Warcraft expansion would bear that name (and perhaps focus around the events that were set in motion by The Great Sundering). Well, it wasn't long after that WoW.com reported the discovery of new Halloween masks in the game files, depicting two races that will remain nameless until after the jump. (Hey, I don't want to be "that guy" that spoiled you.)
When it comes to "leaked" information, WoW.com has hit just about as many as it's missed. That's why we're reporting that they've reported inside sources have leaked the big one, and "confirmed" to the website what the next playable races in WoW will be (and for which faction). You can check out the site's post here, or click through to the jump if you'd like to know what WoW.com claims the next playable races will be.
Quoted directly from WoW.com:
Our sources have told us that the new races of Cataclysm will be:
Worgen – Alliance
Goblin – Horde
