Red daleks in Doctor Who Season 4 finale

There's been a lot of speculation about whether Davros was going to crop up in the season 4 finale of Doctor Who, but the possibility of that being the case was made all the closer for us when we were told by a reliable source that the Mill FX house that does the effects work for Doctor Who has been playing around with daleks that are to appear in the finale of the current season, daleks that might (for some reason) be red.

The details are up for question, but the fact that the daleks are to appear in the finale now seems to us to be a fact.

Mind you, it wouldn't be the first time we've been wrong.
