Fellowes also might be apologizing to fans in the near future as he might have to hand showrunner duties off to someone else as NBC has tapped him
to write a new series, which he'll begin once writing on season four is finished. "If I'm doing a series at NBC, I would not be able to write all of Downton
and all of that series at the same time," he says, adding, "I'd prefer to do everything on my terms [but] the business of life is learning that you can't lay down the terms. If Downton
goes on -- of course that's not my decision -- then it would be with other writers. And one of the tricks is to recognize when it's time to come to an end. Some things go on for 20 years ... but I just don't see Downton
being one of them."
