The BBC America season Premiere of Dr Who will be on Saturday April 23, 2011. . I came across a website that list some of the upcoming episodes with plot summaries of them . But beware the writere of the of the page also warns some should be treated as rumor so be warned and not disappointed.
Doctor Who Series Episode Guide 2011 2012
Looks to me that the first episode according to the site is called
“3201 Deserted
3202 Project Blue Book
214 230411 By Steven Moffat
300411″
Of course these are suggested titles and may not be the real ones. If so this is the one that the BBC actually shot in the States.
