American Horror Story fans have not yet been introduced to season 3's Coven yet but co-creator Ryan Murphy is already planning out season 4.

Speaking to E!Online, Murphy teased that viewers may be teased with season 4's concept in the last episode of Coven.

"Right now I'm writing episode 9 or 10 so I will definitely get that in," he said. "I always thought it would be cool to have the season end and the last image will be this is what the next season is about and you'll get the title."

Season 4 will likely be star Jessica Lange's last season on the horror anthology series based on previous comments.

"I think that would be the absolute stop date," Lange revealed, referring to season 4. "One more after this, because . . . it takes up a lot of time. It's a big commitment every year. There's a lot of other things that I want to be doing."

Before anyone worries about Lange leaving the show, there is still a full season ahead in which she stars as "Supreme" witch Fiona Goode. Critics that have seen the premiere episode have praised her performance and compared her to her season 1 character Constance Langdon and her Asylum character Sister Jude.

"Lange's supreme witch Fiona Goode shares more similarities with Constance than Sister Jude and it's great to behold," said The Huffington Post. The review also notes that this season has a "fun premise" and compares it to Buffy the Vampire Slayer and True Blood.
