I would place my chips on Universal's next venture being a permanent HHN experience or mini-park that's open year round. HHN is what Universal is known for, they have had 20 years experience creating haunts, and they are the best in the country at it -- it's in their DNA. HHN is a HUGE moneymaker. Granted, they are mostly locals.
All Universal has to do is snatch up the theme park rights to all available horror IP's... Freddy, Jason, SAW, Steven King's IT... everything. Combine that with the classic Universal Monsters... have permanent haunted houses and horror-based rides attractions. It's something ONLY Universal can do. Park opens at 6PM every night.
