The Oscar-nominated actor has finished filming his latest turn as the famous detective, with the new episodes expected to air in January.
However, fans of the BBC drama might be concerned by his recent comments to British GQ, in which he admitted that wrapping shooting felt like “the end of an era”.
Cumberbatch, 40, told the November issue of the magazine that although he would “never say never” to reprising the lead role alongside Martin Freeman’s Doctor Watson, the popular show “felt complete”.
“It might be the end of an era. It feels like the end of an era, to be honest,” he said. “It goes to a place where it will be pretty hard to follow on immediately. We never say never on the show.
“I’d love to revisit it, I’d love to keep revisiting it, I stand by that, but in the immediate future we all have things that we want to crack on with and we’ve made something very complete as it is, so I think we’ll just wait and see. The idea of never playing him again is really galling.”

The fourth series of Sherlock will consist of three episodes, which the BBC has promised will be “the most shocking and surprising yet”.
