I got the feeling it was going to be a 3 part season finale, so 1 just to set it up seems ok (though I can't believe I didn't see it coming, in the Face of Bo episode I got there was going to probably be a season finale with another 'doctor', and that he was going to have to be a baddy, but didn't see the Master until they made it blatently obvious - DOH!).

I'm quite looking forward to them running a story for longer than to episodes, I just hope they can make it work.

Why get rid of Derick Jacobi though? I was just getting into wanting to see him be a baddy and they got rid of him. Pah!
