Dr Who speculation (update 3)

The BBC are showing some teasers about the last episode of this series of Dr Who, you can see one here and it is safe to say that Mickey Smith is back, he is definitely one of the prisoners in the Dalek prisoner camp. And if you watch here then you will hear that Davros's plan is that "people, the planets the stars will become dust and the dust will become atoms and the atoms will become nothing... This is my ultimate victory, the destruction of reality itself". One of the greatest loopy villain lines of all time. I can hardly wait until 6:40pm
