Unfortunately, we may have quite a while to wait before we find out more about Hopper or see any of the plots for Season 3. No premiere date has yet been announced for the next batch of episodes, but the odds are pretty good that we'll be waiting until 2019. The hiatus between the first season and the second lasted for more than 15 months. Given that Season 2 premiered on Netflix at the end of October 2017, we may be waiting until early 2019 for Season 3. Only time will tell. David Harbour is currently in the running for a Golden Globe for his performance as Hopper, and we're really hoping he wins for one big reason.
