They've not resolved the storyline with who's gonna be the next head of hospital, theres still a chance Bailey could end up there. But she wanted to devote more time with the clinic and thats what she's heading up right now. And yes she's got the new grey and the new interns and her husband if he comes back.
As for P.P. theres no chance its gonna bomb as long as they find the right time slot, hell even if its right after Greys. its gonna do good.
i love the show to death sadly
