Fans of the BBC miniseries "Sherlock" better believe the saying "Good things come to those who wait." Even with fans going through an "emotional upheaval," as described by show co-creator Steve Moffat, over the long wait for season four, there is still no definite premiere date.

"Sherlock" writer, co-creator, and producer Moffat confirmed that they will not be filming until 2016 and probably will not air before 2017. Scheduling had been difficult for the cast and crew as the show's main actors, Benedict Cumberbatch (Sherlock Holmes) and Martin Freeman (John Watson) have been busy with their other projects.

Even after wrapping up filming on the epic fantasy trilogy "The Hobbit," Freeman is not slowing down and has signed up for FX's dark comedy "Fargo," a black comedy series based off the cult hit film of the same title which launched last year.

Cumberbatch, on the other hand, just starred in the Oscar-nominated "The Imitation Game" and has been confirmed by Marvel Studios to portray Doctor Strange in next year's movie.

Despite season four of the British crime drama not having a confirmed date yet, Moffat has started revealing some plot lines for it already and said that the new season will be about consequences. Digital Spy UK, quoting an interview with Entertainment Weekly, reported, "It's dark in some ways - obviously it's great fun and a Sherlock Holmes romp and all that - but there's a sense of things coming back to bite you. It's going to be more of an emotional upheaval. Hopefully enjoyable and fun, all the things Sherlock must always be. It will be tough at times."

BBC's "Sherlock" is a contemporary take on Sir Arthur Conan Doyle's detective adventure stories of Sherlock Holmes and his friend and ally John Watson. It first aired in 2010 and has since been nominated for various awards, including the BAFTAs. It currently has nine episodes, three for each season.

Season four has been confirmed for another three episodes.
