There have been 'bare coasters' built since Hulk and Dragons were first made at other Universal Resorts..like for example. Flight of the Hippogriff (Japan and Hollywood); Japan - Vekoma, Hollywood - Mack Puss In Boots (there are sections where it is pretty much bare naked supports that can be clearly seen) in Singapore Hollywood Dream in Japan (B&M Hyper); can be seen bare naked through multiple parts of the Japanese park I wouldn't even classify Hulk as the icon of the park. That, goes to the lighthouse, much like how the Globe/Arch is for USF, USH, USJ, and USS. I would say, it's not impossible that we see another bare naked coaster. You can't hide everything from the guest, even if they tried.
