God of War III speculation or pointless material? SPOILERS!!!

Ok, So I just beat God mode in God of War. After beating it I recieved a second number to call and it was (SPOILER)Kratos said that he has Ares' soul trapped and kept in a temple that even zeus didn't know about and that one day will use it on him. Also, I also unlocked the Fate of Titans about what happened to Kronos. It showed a small clip (SPOILER)of his skeleton in present day with helicopters and military tanks going to it and says that a new hero will emerge. So, I haven't seen anything but is it possible that either of these may play in assisting Kratos in taking down Zeus and Mount Olympus in God of War III?

The former probally has something to do with GoW 3, but the last one, probally not. As for the second(SPOILER)Setting up a sequel perhaps?
