It could be set before series 4 as there are also other Daleks from other points of the classic era. In the first trailer when Missy held up the mirror and saw a red light reflecting it looked like a Dalek, I know the red light bit if different but I just thought it may have been a Dalek. You can add the series 9 trailer onto this blog.
