FX U.S. has renewed Fargo and Louie. The ten-episode second season of Fargo will feature an entirely new cast and will be set in a different time period. Louie was renewed for a seven episode fifth season, which will premiere next spring.
In addition, FX announced that the tenth season of It's Always Sunny In Philadelphia will premiere in January, later than originally scheduled. American Horror Story: Freak Show will launch in October.
My guess is FX Canada and FXX Canada will air the same shows next season as they do now. Hopefully, Rogers Media will make it easier for other BDUs to pick up FXX Canada. Right now they have it exclusive to Rogers Cable.
