After a series of "specials" in 2009 Doctor Who is set to come back in 2010 with a full series and a new Doctor. Today the BBC announced that Matt Smith will be replacing David Tennant as the 900-something year old Timelord. Here in the US, if you've seen him at all, it was probably in the PBS broadcast of Ruby in the Smoke with Billie Piper.
