This one's a bit of a shocker, since the show has been such a big (and cult) hit! Netflix announced this week that "The Chilling Adventures of Sabrina" will now end with its 4th season ("part four") later this year. No release date officially, but fall seems likely.
Netflix and showrunner Roberto Aguirre-Sacasa had this to say in a statement:
“Working on ‘Chilling Adventures of Sabrina’ has been an incredible honor from day one. The cast, beginning with Kiernan as everyone’s favorite teen witch, has been an absolute joy. I am beyond thankful to the crew, writers, editors, assistants, and everyone for pouring so much love into this dark dream of a show,” said Aguirre-Sacasa. “I’m also grateful to our partners at Netflix, Warner Bros., Berlanti Television and Archie Comics for letting us tell the story we wanted to tell, the way we wanted to tell it. We can’t wait for everyone to see Part Four.”
The show's Twitter released a few images from the upcoming final chapter for fans:
