Frankie and Kevin
Steve and Ola
Mark and Karen
Based on what we're currently seeing, Jake and Pixie ought to be in there - and maybe Caroline. However, I'm working on the basis of one contestant who is great from the off (Frankie - who is also paired with a popular pro) and then looking at the other celebs and guessing who can combine getting the audience to vote with them with an actual ability to dance and improve week on week.
I think Jake may have peaked too early & may struggle to lose his Eastenders character in the eyes of the public when it comes to the dances where that is less appropriate.
I'll probably be totally wrong - but I thought I'd guess anyway!
My own choice for the final would be Frankie & Kevin versus Steve & Olla. I would find it hard to pick a third. Steve is a gamble because he may or may not start to find it easier to pick up the routines as the show progresses. However, if he gets better at that, then I think he has a good combo of natural ability and THAT smile!
