My assumption was always that Universal Monsters's inclusion in Vegas was the death knell for them, at least in Orlando. I'm curious how they'll approach that IP slot in the future though, since it's been a while!
As for sequels, I think Slaughter Sinema is a safe bet (Mardi Gras Murders? Killer Kringles?), I feel a little less safe but still willing to bet on a scarezone adaptation (Invasion? Path of the Wicked?), and a Legacy Sequel (PsychoScareapy was referenced in the Tree Graveyard Boutique...).
