If the producers have any sense, they won't change too much at once. It's always a risk making sweeping changes. Many viewers are quite conservative and don't want to see the programme changed out of all recognition.
We know Ola's going.
I wouldn't be surprised if Aliona decided to go out on a high, as the first pro to win twice and after what seems to have been her favourite series to date.
I wouldn't be surprised if Kristina or Natalie left either, though I'd love it if Natalie stayed and got another contender. Unfortunately, probably more than any other femalepro, she most likely gets assigned her partners based on height rather than any other criteria.
I don't think Anton or Brendan will leave until they're pushed, and I don't think they'll be pushed anytime soon. I think the powers that be like having these two remaining pros from the first series. I wouldn't mind if Anton left, I'm not fussed about Brendan either way.
I'd love it if Janette and Jo were to swap roles next year. I think Janette is a bit lacking in technique, and Jo was wasted this year.
I admit Kevin can be irritating - he needs to learn when to tone down the personality - but everyone has their quirks that can irritate. I don't get all the Clifton hatred.
In theory, I wouldn't mind if Len left but in practice, it would depend very much on who replaces him. I doubt more than one judge would be changed at a time.
