HBO recently ordered a new season to be made and rumored to be arriving in 2018.
Looks like HBO's gamble hoping this would be their big replacement for Game of Thrones ended up paying off since the weekly viewer average is higher than what GoT did for its first season. Also doing a lot better than True Detective did for its first season.
