Conformation of A Doctor Who Christmas

My suspicions are confirmed, Russell T Davies in SFX181 says Theres the Easter one [Planet of the Dead] and then a big gap, and then the other three are going to go out around Christmas time/end of the year. It ends in a two-parter. Theres a very strong link between the last three specials. Its not a three-parter, but theres a strong connection...
On how Steven Moffat will start Series 5 he says Theres a strong end and then theres a very strong beginning for him. It's literally one second later!
