Richard E Grant has just been in Doctor Who (and was abit rubbish to be honest, even since those unbarable Argos adverts he's been going downhill!). And it obvisously won't be John Hurt, because he's just to big. I hope they pick a relative unknown again, someone without to much baggage from other known roles.
Matt's Doctor + Amy and Rory has been my favourite period of new Who by a mile, they just seemed to click together - haven't enjoyed Clara anywhere near as much, maybe it's the correct time for Matt to leave. (I'm hoping Clara will go too).
