Downton Abbey will be back for its fifth season on January 4, US broadcaster PBS said - but the return date for another hit British series Sherlock is up in the air.
PBS chief executive Paula Kerger said of the show starring Benedict Cumberbath: "We will have to wait to know when it's finished and available."
All episodes of Ken Burns' The Roosevelts, for instance, will be available for streaming the day after the first episode airs on September 14. "Downton Abbey will have some surprises in it. I think you know what's going to happen to the Roosevelts," said Ms Kerger.
