Who will be the new Doctor Who

With the announcement that Matt Smith is leaving Doctor Who at the end of the year it's now a guessing game as to who will become the 12th Doctor.

I hear that the Doctor will regenerate at the end of the 2013 Doctor Who Christmas Special and the new Doctor will start in 2014

A few names I have seen mentioned so far are Hugh Laurie, David Harewood, Olivia Colman, Sean Pertwee, Martin Freeman, Ben Whishaw and Joseph Mawle
