They are not going to have a Christmas Special, but a new year's special! One or two weeks ago they decided to put only to couples in the final to compensate the extra elimination of Jimmy Tarbuck. I'm curious though what they are going to dance next week then. They only have one ballroom or one latin dance left. It's going to be a new year's special because the final is the day before Christmas eve, therefor too little training time after the final. You are right though about series 3 competing with series 4. I'm confident, and I hope, that Colin and Erin and Ian and Zoe will be back. I wanted to win Colin and Erin last year too btw.
