Here are the titles and writers for the up coming series 4 of Doctor Who:
The Unknown Foe (Russell T Davies)
March Of The Cybermen (Stephen Greenhorn)
Coleman Enterprise (Tom Mcrae)
Controller Of Time (Keith Temple)
Controller Of Time Pt 2 (Keith Temple)
Dalek Story Pt 1 (Helen Raynor)

Trial On Gallifrey (James Moran)
Ice Palace Pt 1 (Steven Moffat)
Ice Palace Pt 2 (Steven Moffat)
The Creator (Russell T Davies)
Unholy Machine (Russell T Davies)
New Time War (Russell T Davies)
This isn't definitely certain, most of the titles are likely to change, even if this is the working list.
And of course there is going to be one major villain at the end of the series.
Any ideas on who that might be? Feel free to post below.
There have been rumors all over the Internet that Russell T Davies will be wrapping up his Time War story arc after series 4, but there is not any solid evidence of this yet, just a load of speculation.
Other rumours i have found are:
One episode will be called Planet of the Ood. Rose will return for David tennants last episode; well he's been rumoured to be leaving at the end of series 4. The Nimon will return. The Cybermen will return, people are thinking this dew to an update on the Cyber Corporation site, which can be found HERE . The judoon will appear in the voyage of the dammed and finally Dalek Caan will return.
