I think we'll at least see some new men next year. 2 for AJ & Kevin and possibly 3 if Anton becomes a judge.
Kai from DWTS Ireland is a definite and I'd personally like a Northern European male pro, we've got the Mediterranean hunk quota covered. Definitely think we need some fresh blood.
I reckon Janette is the only woman likely to leave. Karen probably will call it a day after next series and maybe some of the others depending where their lives are at. I love Oti as a dancer/choreographer but I also am beginning to think her time is up soon - in the last 5 years, she's had the best male celeb ever, first ever contestant with a missing limb and then two winners in a row. Nothing left to achieve.
