Daleks in Series Six - Yes or No?

Hello. Recently, Steven Moffat (head writer and producer of Doctor Who) was asked whether the Daleks would return in Series Six and when they would appear if they were not in the series. Steven replied rather inwardly by answering:
"Don't count on it unless they pop up in episode 13. Maybe as a guest moment.”

He then elaborated by saying:
"There’s always a danger that the Daleks are a diminishing return. They are the Doctor’s most reliably defeatable foe. How do you stop that being the case? We will bring back the Daleks eventually, but I want them to come back in a really brilliant way."
So, it doesn't look promising for the Doctor's deadliest foe. Another rumour states that the Daleks will reappear in the Christmas Special after Series Six comes to an end. But we'll have to wait to find out what exactly happens on the subject on the Daleks in the near future.
