'I could imagine we'll come back and do Sherlock fairly often for many years,' says showrunner.
Sherlock boss Steven Moffat believes new episodes of the hit BBC drama series will continue to be produced on a regular basis for years to come.
And although the 54-year-old admits he will eventually leave his showrunner role on Doctor Who, he cannot foresee an end to his involvement on Sherlock because it "doesn't swamp his schedule".
Speaking to Assignment X, Moffat is reported as saying: "Eventually, I'll stop doing Doctor Who because it stops me doing anything else.
"But Sherlock doesn't swamp my schedule."
He continued: "I could imagine we'll come back and do Sherlock fairly often for many years, rather than very often for a few years."
It is believed fans will now have to wait until 2015 for the next episode of the detective drama starring Benedict Cumberbatch and Martin Freeman, with Moffat previously saying that discussions were ongoing about filming dates.
