When they say "Iron Man Thrill Ride" it's not like they are going to just put some off-the-shelf flat ride and theme it to Iron Man. At least that's not my impression.
This has been discussed as an E-Ticket attraction. For Disney, a "Thrill Ride" is something like Indy, Space Mountain, Big Thunder, RSR, Tower of Terror. Not a 500 foot, 12 inversion coaster.
