Blizzard has 3 Current Projects?

From the Inquirer:"We hear there are three things the company is working on, obviously WoW, Starcraft II, and a third top secret project that is not the oft-rumored Diablo III. If you happen to be walking behind Blizzard folk at AGDC, you might hear something that sounds like this.

Blizzard Employee 1: What are you working on?
Blizzard Employee 2: Starcraft II, and you?
Blizzard Employee 1: I am working on Hydra.

So now you know, start your search engines boys and girls, you have something to go on now. We hear internally it is called "Project Hydra", but we won't hold you to being so formal"

This is amazing... Unfortunately I think this could just be another expansion. Blizzard has said in previous interviews that code names like this are really meaningless. We probably shouldn't read too much into this.
