I'm more eager to see Series 10, as I really love regeneration stories, and cannot wait to see who Twelve changes into.

I'm also curious to see what happens in Series 11, with a new producer/head show runner, and a new Doctor.

You realise at this point there is no confirmation that Capaldi will leave at the end of series 10.

Even if it is true, would you really put anticipation in one series over another based on what would happen in a single episode? If it is true, then series 11 would have the other kind of special episode with the dawning of a new doctor in it's favour.
