While I agree that the IP holder would probably want to hold off on adding any new material to the house (no spoilers), I disagree with your first part.
Jan/Feb used to be a good dumping ground for crap movies. That's changed a bit in the past year or so, especially when it comes to horror. Split and Get Out were both released in the first two months of the year, and are two of the higher rated movies so far.
It could just be that they saw an overly crowded October, and decided to punt to a much less competitive time.
If we do end up still seeing it, it will probably be very similar to the HHN25 house.
