That's it for Series Four of Doctor Who, and the show won't be back on our screens until Christmas. However, last night's episode, Journey's End, featured a short teaser trailer at the very end, and here it is. If anyone wants me to, I can upload subsequent trailers for this episode when they emerge. Message me if you'd like this. Sorry about the point near the beginning of this video where the picture breaks up, I've seen this on a couple of other videos on YouTube, and I'm told there's no fix. :-( P.S. No title has been revealed for this episode, so for now I will just use the phrase seen in this teaser: The Return of the Cybermen.
