New Doctor Who To Be Announced in August or September

According to Britain's Radio Times, The BBC will announce the casting of a new Doctor Who in time for principal photography to begin on the Christmas Special late this summer or early in the fall. Here's how they put it:

BBC insiders have told RadioTimes.com that filming on the Christmas special – to be followed by the full series – will not take place until the autumn – probably August, or even September. According to sources the identity of the Twelfth Doctor is almost certain to be announced just prior to filming, which means that it is very likely that the new incarnation of the Time Lord will not be unveiled until late summer.

The Radio Times used to be operated by The BBC, and so have plenty of insiders to pull from. Speculation has run rampant since Matt Smith announced that he would be leaving the series at the end of the year, as to who might replace him on the long-running sci-fi staple.
