It seems the BBC are giving Doctor Who a rest after season 4 next year...
The fourth season is still scheduled for spring 2008, with Catherine Tate as the new companion, but only three special episodes will air in 2009, written by executive producer Russell T. Davies.
The fifth full season, strongly rumoured to be sans Davies and star David Tennant, will air in spring 2010.
Jane Tranter, Controller of BBC Fiction, commented: "Doctor Who is one of the BBC's best loved and most successful dramas. Its journey over the past three series has been one of the most ambitious and exciting that we have had, and I'm delighted to be able to confirm not only three exciting specials for 2009, but a fifth series in 2010."
Menna Richards, Controller of BBC Wales, commented: "The success of Doctor Who is a fantastic tribute to the dedication and expertise of the production team at BBC Wales who have worked on the project from the outset. This announcement is marvellous news for all involved, and more importantly for the programme's amazing fan base and audience. BBC Wales is looking forward to producing the fifth series."
It makes sense to give Who a rest after a hectic few years, and I'm sure the three special episodes will be enough to satisfy fans in 2009. So, a wise move by the BBC, methinks...
