Joy and Barbara are long time friends, so I doubt that she's going anywhere. Joy is actually my favorite on the show, tied with Meredith. Barbara said, yesterday, I think, that in the beginning, she was supposed to be there two or three days a week, and Joy the others. Joy worked out so well, that they decided to keep her everyday. I like Elizabeth, but since her politics are totally opposite from mine, I wish she'd keep quiet.
I definitely won't watch anymore if Patricia Heaton comes on board. Like Broadway, I had enough of her when she always looked so pained, and ran her mouth, during the Schiavo thing.
I don't think that Kathie Lee would be interested, even if THEY were, But I'd definitely watch her.
