But with Black Mirror being immensely popular on Netflix, we’d like to assume that Season 6 will happen eventually. So, with that in mind, when could Season 6 possibly come out? Well, Season 5 came out in June 2019, and “Bandersnatch” came out in December 2018. Season 4 came out in December 2017, but Season 3 came out in October 2016. So, given that timeline, we would normally expect a Black Mirror season around the fall or Christmas period.
And there is always the chance that we could see another season later this year, but that seems extremely optimistic, as it's looking very uncertain at this point, with very little information to go on.
