I kept wondering if it was implied The Doctor would regenerate, but how would she have recognized him?
Loved this episode. I can't pick out any specific points I just... loved it. The only part I really didn't like was the part where Donna's "kids" vanished and she freaked out.
I'd go ahead and give this a 9/10 but, as I promised earlier, I'll give it more time before I give my final vote.

I'm considering going ahead and watching the next one just to catch up like before...
EDIT: I stand by my decision. I've voted 9/10.
