Harbour doesn’t confirm the release per se, but it’s based on his opinion considering that the script is still being written, indicating that it will be a while before it even enters into production. “I mean, one of the things that’s annoying for fans is that it takes us a long time to do them. Like, you probably won’t get [Season 3] until sometime in 2019. But also part of the thing is, like any good thing, they need time. And those guys work so hard. I mean, they just sit in their apartment and write for 12, 14 hours a day.”
We guess that makes sense, and to be fair Netflix does have a lot on its plate for 2018, with various shows expected to return for new seasons, like their Marvel TV-series, along with the final season of House of Cards sans Kevin Spacey. In the meantime for those who can’t wait that long, reviews of Netflix’s German-based TV series “Dark” has been rather positive, with some comparing it to Stranger Things, so perhaps that could be worth a gander.
