Here's the write-up from the online version of the Radio Times.
http://www.radiotimes.com/episode/cq6k6j/doctor-who--the-time-of-the-doctorInteresting that it says Matt's now bumped up to the 13th Doctor, rather than to the 12th. I wonder if that suggests the Valyard's around somewhere. Or is there yet another unknown Doctor?
The cast-list doesn't really tell us anything we don't know - the Daleks, the Cybermen and the Silence are all going to be around.
