Some information about Davros being in series 4 has been released by someone who has a background of being right about things in Doctor Who, and he had this to say about Davros.
"All i can say is that Davros is back and he is stronger than ever, with more hate and vengence for the Doctor he is going to be a hard challenge to beat, but i can assure you the newly designed Davros is like never before, and lets just say Rose's return is part of Davros's plans"
Wow that is breaking news!!!!
