Impatience and Doctor Who

Why is it that people can't wait for anything these days. I'm made up that we have Peter Capaldi as the new Doctor , but couldn't they have kept it under wraps until the next generation. I've loved Peter Capaldi  from his role in the funnily atrocious Lair Of The White Worm , a Ken Russel excess fest full of single entendres , then Local Hero , and his probably crowning character as the swearily inventive spin doctor Malcolm Tucker in The Thick of It.
So we now know robbing Matt Smith's exit of a huge chuck of suspense. If I were to choose some music to play it could be the Theme from Local Hero but instead I'm going to post Brian Eno#s "This" where the word this is repeated as the rhythm to the song. Has no bearing to what I'm talking about but I dont really care,
