Even though nothing is confirmed, but the report claims that Steven Moffat while responding to the fans of China appealing to him for expanding the number of episodes, responded by saying: "No, it's a waste of time, sorry, China" (as quoted by Enquirer Herald).

Return of Irene Adler

Return of Benedict Cumberbatch as Sherlock Holmes in "Sherlock" Season 4 is something that fans can't wait for.

Earlier on, it was rumored that the show might return by Christmas 2014, but the recent reports about the scheduling indicate delay in "Sherlock" Season 4 premiere.
