I doubt Katy Perry could do it, probably another year of touring for her. Simon will stay in the US I am quite sure. I dislike Gary Barlow more and more on this show, but realistically I see him staying, but I doubt Kelly will be here next year. I think it will/could be...

Gary Barlow (but would be good if he could be replaced, not sure who with)
Lily Allen or Nicole Sherzinger
Tulisa
Louis Walsh

Would be nice if Simon Cowell could come back and be a guest judge on a few shows aswell, especially maybe the first live show, week 5 or 6 and perhaps the final to listen to what he thinks how the contestants are doing.

People like Katy Perry, Gaga, Rihanna and so on have no chance, they are too succesful as stars already and will probably be touring again.
