So I can now confirm that Doctor Who returns to BBC One during the Easter weekend on Saturday, 30 March, 2013 as far as we know this will also be the return date for BBC America but this is as yet unconfirmed.
The Doctor is back in a fantastic adventure written by the show’s lead writer and executive producer, Steven Moffat. Matt Smith will appear alongside new companion Jenna-Louise Coleman in a series of adventures written by showrunner Steven Moffat, Mark Gatiss, Luther creator Neil Cross and celebrated author Neil Gaiman who will be contributing a new episode featuring iconic enemy, the Cybermen.
Moffat has promised us that in terms of Doctor Who, 2013 will be a ‘tremendous’ year and that it would include a "modern urban thriller", a "base-under-siege story", an "absolutely mental" period drama and a "fanboy-pleasing" finale.
A one-off special - celebrating Doctor Who's 50th anniversary - is expected to follow the eight new episodes in November.
