Ok, I'm just going to write down all the rumours I've heard so far regarding the remaining specials, and I'll write confirmed if the BBC have confirmed them.
Planet of the Dead - airs this weekend so I'm not going to bother.
The next special after that will probably air in November (says Russel T. Davies on BBC Breakfast, Tuesday 7th April) and MIGHT be called "Water on Mars". The title will be shown at the end of saturday's special. IF that is the correct title, then it is POSSIBLE that the Ice Warriors (who live on Mars) may make a return, as both water and mars suggest it.
The REMAINING TWO episodes will most likely be shown over Christmas, and will probably be a To Be Continued. The companion for BOTH is CONFIRMED by RTD (BBC Breakfast, Tuesday April 7th) to be Bernard Cribbins, who played Donna's grandfather Wilfred.
