BBC官网的消息，大意是第四季08春出，第五季要2010春再出，09年只有DT主演、RTD主笔的三期特别节目。
实在搞不懂BBC为什么这样安排，都说DT、RTD第四季后将双双走人，但也用不着把节目搁置一年吧，会不会是怕观众对他们的版本印象太深，一下换新人观众接受不了，所以干脆冷处理一段时间，好让接替的新人有更多时间作充分准备，并让观众稍稍淡忘老人马对新人多一份期待呢？不明白

Doctor Who to return for fifth series in 2010. After months of media speculation, the BBC can confirm that the BAFTA award-winning Doctor Who will return for a fifth series in Spring 2010.
Viewers are in for a treat this Christmas, as a special episode starring David Tennant and Kylie Minogue will be broadcast on BBC One in December 2007.
Series Four, which went into production in July 2007, will hit UK screens in Spring 2008, followed by a special episode for Christmas 2008.
In 2009 Doctor Who will return with three specials starring David Tennant, with Head Writer, Russell T Davies.
The full-length fifth series will transmit in 2010.
Jane Tranter, Controller, BBC Fiction, says: "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, BBC Wales, says: "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."
Following the critically acclaimed season three finale, the BBC has announced that Catherine Tate is set to return to the TARDIS for the complete 13-week run of series four, reprising her role as Donna from the 2006 Christmas special.
Freema Agyeman, who won praise for her portrayal of Martha Jones in series three, is also set to return mid series four.
