At Blizzard 2009, CEO Mike Morhaime (below) revealed the mysterious Project Hydra, which was supposed to be the codename of the next gen MMO the company is working on.
As it turns out, he confirmed that Project Hydra is actually the codename for Diablo 3. It means nothing on the MMO was revealed or leaked… yet. Seems like Blizzard really signed all their staff to death oaths, as rumored across the Internet… lol.
