Sherlock season 4 will air in 2017 on BBC One and PBS.
Hopefully, fans can expect to see them as Holmes and Watson for many years to come.
Their friendship has definitely been tested over the past few years, what with Sherlock dying.
Though the actors are keeping busy with other projects (Cumberbatch will star in Marvel’s Doctor Strange later this year), they still take a bit of time out every year or so to return to the roles of Sherlock Holmes and John Watson.
