Sony announced one the Furies, Megaera, in God of War Ascension at PAX Prime 2012. The Furies are the main antagonists of God Of War Ascension. They're basically the bond keepers for Ares. Six months after Kratos killed his wife and child he begins looking to get out of his deal with Ares. I think you can see why the Furies and Kratos might not see eye to eye.
Fact: When I first read about the Furies I misread it as furries. That would have been a very different game.
