Sherlock Creator Hints Season 4 May be the Last in First Set Image Reveal

The cult following for BBC's Sherlock has been strong since its first airing back in 2010. The six new Emmy Awards nominations add to the proof that the show is one of the forerunners on BBC One.

However, it seems that nothing really lasts forever. And for Sherlock, its future may fold while the show is still on a good high. Executive Producer Steven Moffat confirmed this with Telegraph:

"I don't know how long we can keep it going. I'm personally willing but I'm hardly the main draw. I would be moderately surprised if this was the last time we ever made this show. But it absolutely could be."

According to Moffat, one possible reason is the fact that Benedict Cumberbatch has become a renowned name all over the world. And the fact that a fourth season is still possible may be due to the actor's loyalty to the show's fans.

This comes in tandem with the first set image revealed for the show. The image, seen in the link above, shows Cumberbatch as Sherlock together with a bloodhound. He seems to be instructing the dog—or perhaps he's contemplating his next move with his trusty companion by his side?

Still, as a nice ending note, Moffat remains positive that the series can continue later on. That is, once the filming scheduled conflicts for Cumberbatch and Martin Freeman (who plays the role of Doctor Watson) clear up.

Sherlock will air sometime in early 2017.
