Hey nonny, are you talking about a secret fourth episode for Sherlock that was supposed to come out at some specified time to be revealed as needed after series 4 aired?
Sadly, I don’t think television really works that way. It costs a lot of money to make a tv show, actors and crew must be gathered, things filmed, and shows scheduled and announced. It just doesn’t make sense to create an episode that you just randomly throw up one day without any advertising or planning.
Benedict is busy doing the MCU avengers movies for awhile, along with a HOST of movies he has scheduled. Martin is similarly booked, and Moffat and Gatiss have announced plans to ruin, um reboot Dracula as their next project. Sadly, I don’t even see a series 5 being planned any time soon.
I dunno, friend, it pretty much looks like they wrapped up BBC Sherlock with their weird Mary-voiced over montage at the end of S4.
We can enjoy what exists of the show, and enjoy making fanworks, and discover other adaptations of Holmes and Watson, but I’m not really expecting any new content for this version.
As far as I’m aware people are still engaged in EMP, though more so as a coping method for s4. I’ve seen a few theories and ideas as to what s5 will be if we get it, nothing extreme meta length however (I’m taking m theory here). Check my archive of #EMP and #s5 for those posts
The general consensus it looks like is that s4 is all we’re going to get for at lest the next 3 years. Possibly for even longer if BBC Dracula takes off. And even longer if Ben and Martin keep getting picked for roles (which they will). Check out #bbc dracula for discussion about that. (Warning for wank)
Personally, I would say the show is done and we might be a one off special in the next 5 years (depending on the above). I don’t think we’ll ever get a full 3 episode season ever again in the nearish-BBC Sherlock normal-haitus future.
