I think THING has a very high chance of coming out. It's based on a separate movie than the original (though the same series obviously) so I'd consider it fair game. And we all know how much A&D loves The Thing, not to mention how much the executives love promotional tie-ins...
Strong rumor that's been making the rounds - a pirate ship house located in the Jaws queue. Think about it - it's cramped, musty, claustrophobic, dank - and could make excellent use of water effects (right next to the lagoon) as well as the cargo net scare. Pirates isn't a theme we've ever really seen at HHN, yet it's one that holds great potential...
