New Doctor Who Announcement Coming Sunday

MSN UK Entertainment revealed that a new announcement in regards to Doctor Who is imminent. MSN UK Entertainment tweeted, "#DoctorWho fans. There will be an announcement at midnight. That's all I'm saying..." Of course, this tweet led to immediate speculation that the new Doctor Who might be announced tonight at midnight UK time. However, Starburst Magazine is reporting that the announcement will actually be for a show that will air on Sunday that will reveal the new Doctor Who. The BBC has reportedly shifted this Sunday night's 7 PM edition of Celebrity Mastermind on BBC One to make room for the 12th Doctor Who announcement. The announcement will reportedly be made in front of a live studio audience, who were told they would be attending a pilot for a show looking back at the fifty year history of Doctor Who. Any guesses at to who the new Doctor Who will be?
