Okay, after lots of reading and scrutiny, it looks like the four symbols go along with four types of characters she mentioned. (Mind - the hand with the eye on it), (body - the sword), (nobility - the crown), and (corruption - Yin/Yang symbol). But that's just my interpretation of it.
Peter Molyneux won't comment on too many aspects of the game. From what I've read, he talked about Fable before it came out and named a lot of things he was going for, that he didn't get incorporated into the game. So, thats why he won't talk about Fable 2 that much.
Here's a link the the article.

Don't get your hopes up, but rumored release date at Lionhead is December 6, 2006. Figured I'd put this in here for the people that don't visit both forums.
