The wait for the Hurricane Katrina-focused season of American Crime Story continues.

FX boss John Landgraf told reporters at the Television Critics Association winter press tour that he doesn't know what the next version of the Ryan Murphy-created anthology series will be after the upcoming installment focusing on the Assassination of Gianni Versace, proving that he's just like us when trying to navigate the ever-growing labyrinth of Murphy's portfolio.

A little background: Murphy seems to announce ideas for his true-crime anthology before he even knows what order they'll be in. Following the success of The People v. O.J. Simpson, Season 2 was announced to be set during and after Hurricane Katrina, and The Assassination of Gianni Versace — which debuts this month and will run as Season 2 — was supposed to be the third season of the anthology. Murphy didn't stop there. It was also announced that Season 4 will cover the Bill Clinton-Monica Lewinsky scandal. So what's the deal with those?

"I don't know about the Monica Lewinsky-Linda Tripp story," Landgraf said. "It's just in development and I haven't seen a script yet, so I don't know yet where that's at yet or if it's good enough."

As for Katrina, it still sounds like there are some things holding the show back, including a change in focus, actors' schedules and a shift in the source material. In August, Murphy opted to adapt the Katrina-based book Five Days at Memorial by Sheri Fink rather than the previously chosen The Great Deluge by Douglas Brinkley.

"Similarly on Katrina, as we announced, we took a really different approach and made a deal for a really great book, and that's in active development but I haven't seen a script," Landgraf said. "But I couldn't tell you after [The Assassination of Gianni Versace] what the next installment of American Crime Story will be. It might be Katrina, it might be something else. I can just tell you there will be one."

As for what's next for American Horror Story, Murphy's other anthology, that's another big question mark. But the news here is that Murphy does have an idea cooked up.

"I can't [tell you what the next season of American Horror Story will be]," Landgraf said. "You're going to have to ask Ryan, because I don't know. I know he has something in his back pocket but I don't know."

Typical Ryan Murphy. I guess we'll just have to keep a close eye on his Instagram.
