I'm not sure but I think I recall Ryan saying that Evan and Sarah are the only ones that never died and they will this season.
Thinking about it, he was kind of right, but kind of it is not true, because Evan in Murder House was actually always dead (we saw him die in a flashback), but since he was a ghost, it's like he never died for the viewer.
So maybe Sarah will find her end this season, anyway. For example, the hotel will be destroyed, or something.
