SoooâŚÂ I would just like to say for my fellow tinhatters and hopefuls, that March 8 (of the infamous billboard) is on a Sunday (the day Sherlock usually airs) in 2020 - also coincidentally one year after the copyright on three more of the Sherlock stories ends, including The Three Garridebs. Â
That would definitely make the gap they talk about being longer than normal true - 3 years instead of 2. Â It would also be conveniently after the work for Dracula is wrapped up: Gatiss stating that they started writing in January 2018 and that the project would take about 2 years (x).Â
And all remaining Sherlock Holmes stories will be public domain by 2022, which makes coming back in 2020 Â very feasible for the continuation of the series without copyright impediments.

Arthur Conan Doyle published his first Sherlock Holmes story in 1887 and his last in 1927. There were 56 stories in all, plus 4 novels. The final 10 stories were published between 1923 and 1927. As a result of statutory extensions of copyright protection culminating in the 1998 Copyright Term Extension Act, the American copyrights on those final stories (copyrights owned by Doyleâs estate, the appellant) will not expire until 95 years after the Case: 14-1128 Document: 29 Filed: 06/16/2014 Pages: 15 2 No. 14-1128 date of original publicationâbetween 2018 to 2022, depending on the original publication date of each story.Â

The aforementioned copyright judgement was issued in 2014
The Problem of Thor Bridge became public domain in 2017
The Adventure of the Creeping Man enters public domain in 2018
Sussex Vampire, Three Garridebs, and Illustrious Client become public domain in 2019 (just in time for shooting for a 2020 release date)
Three Gables, Blanched Soldier, Lions Mane, and Retired Colourman in 2021
And the final two: Veiled Lodger and Shoscombe Old Place come into the public domain in 2022.
After that, anyone is free to do whatever the hell they like with those stories without worrying about copyright issues.
Considering all of the above, and Moffatâs absolute love of The Three Garridebs, 2020 is a good bet, I think, for s5. And if a standard 2 year hiatus comes between s5 and any seasons, episodes, or one-offs that might follow it, all the rest of the Sherlock Holmes stories will then be available for use.
