MSN UK Entertainment have just tweeted the following:
@msnents: #DoctorWho fans. There will be an announcement at midnight. That's all I'm saying...
At the moment it is not clear what this announcement may be. It was rumoured that the identity of the Twelfth Doctor could be revealed in August, although showrunner Steven Moffat was still maintaining only a couple of weeks ago at San Diego Comic Con that they had barely started looking. It could also be an announcement relating to the 50th Anniversary episode - fans were promised some exclusive content following the debacle of the SDCC trailer. Or it could even be something hitherto unforeseen
The information will be revealed at midnight UK time, so check back here later tonight
