1. It doesn't fit the current speculation that the last IP is new to HHN Orlando. Also, I put together a list last Friday where the current spec was at, including placing AHS: Cult as basically out. Legacy gave me corrections to make to the list, but moving AHS: Cult to possible was not one of them. Unless we're being lied to, in which case why bother with clues at all, it's out.
2. Regardless of whether or not a press release said tv shows or show, plans can change. I mean, look, they said from the beginning it's 9 houses but we're still speculating on a 10th mystery house based on a code name only. Could the last IP be a tv show? Sure, but there's no reason to limit spec at this point based on an extra 's'.
