“Sherlock” season 5’s future remains up in the air. Either BBC or showrunners Steven Moffat and Mark Gatiss have yet to confirm the show’s return for another season, but fans are patiently waiting and hoping to see their favorite duo back on the small screens.

So, will there still be a chance for a new season? Here’s what we know.

A new season’s future

According to We Got This Covered, Benedict Cumberbatch, who plays as Sherlock, earlier revealed he is up to reprise his role. But, he warned a new season might unlikely happen.

“No time soon. Don’t hold your breath, but you never say never,” he said.

Cumberbatch explained people behind the series are all busy doing other things, so “Sherlock” season 5 might not take shape right now.

Moffat and Gatiss, on the other hand, both expressed their interest to do another season, but the new television series “Dracula” is their priority today. The new BBC show is about to hit the small screens, so it may be the reason behind their silence about “Sherlock.”

From the looks of it, from the lead star to the showrunners, everyone is still busy doing other things to continue the adaptation of Sir Arthur Conan Doyle's novel on TV. The “Doctor Strange” actor himself’s schedule is even full with other projects like another Moffat-led show, “The Time Traveler’s Wife.”

A problematic fourth season

The final episode of “Sherlock” season 4 received a lot of negative reviews.

Critics, fans, and even its own stars didn’t like how “The Final Problem” ended.

Compared to the show’s previous finale episodes, it didn’t have the major cliffhanger fans used to see. It didn’t bear the series’ signature storyline. It wasn’t mysterious and twisted and didn’t manage to engage viewers.

For the first time, “The Final Problem” concluded with a happy ending.

Sherlock and Watson (Martin Freeman) were back in the business, thanks to the latter’s wife, Mary (Amanda Abbington).

One of the most vocal actors who criticized season 4’s ending was Abbington. The 45-year-old star said the showrunners seemed to start satisfying fans by including a lot of fandom stuff to the show’s story.

Alternatively, Martin also noticed injecting fan service to the creative process made the series “less fun to produce.”

Making fans hopeful

Anyhow, although no one of the stars, showrunners, or even the network has yet to confirm “Sherlock” season 5’s coming, Moffat earlier hinted the possibility of a new installment. Is he only making fans hopeful?

In a now-deleted Twitter post, Union Journalism noticed Moffat noted the show’s first four seasons as the “Chapter One.” He posted another photo, saying if ever there would be Chapter Two, the boys “consciously living the myth and battling wrong-doers.”

Whatever Moffat means, it looks like fans have to wait for BBC’s official announcement and confirmation if there will be “Sherlock” season 5.
