I'm pretty sure she signed a new contract.
I think she soon will find out something interesting (in their safe); a big secret about Eric and will stay and use it to her advantage.
I see a big battle for Forrester in the works...between Stephanie and Eric and she will ask her kids to take sides.
I also heard a rumor that she'd fake her death to frame Brooke.
Can't wait to see what's true and what isn't!!
