Speculation is trickling in from the recently concluded Austin Game Developers Conference, with this latest bit regarding the third mystery title that Blizzard may be working on.

According to the source, the information was picked up between two Blizzard employees at the event grounds, with one employee specifically stating that he worked on some project labelled "Hydra." It will be important to note that Starcraft II, prior to getting properly identified, was similarly codenamed "Medusa."

That's the all the information we've got at this point, and it's anybody's bet on what this third project could be. For my personal guess, it might be Diablo 3 - a detail further exemplified that World of Warcraft's Hydras bear three heads (yes, I'm overstepping my bounds a tad bit here). We invite the readers to voice out what this project might be.
