Just looked up those posts:
It seems like the implication is that the price of both TRONs exceeds that of Shanghai's Pirates, not that Shanghai's alone cost more - but either way it's still pretty horrifying. That puts TRON at, what, $200+ Million each? Is that ride really worth twice as much as Expedition: Everest? I know inflation factors, but come on, Disney.
Similarly, I don't expect Cosmic Rewind will be nearly as "visibly expensive" as Shanghai's Pirates - I don't think of Shanghai's Pirates as the unimpeachable high water mark that some seem to think it is, but at least you can tell just by looking at it where the money went. It's still not entirely clear, but it really seems like Cosmic Rewind will be putting much more emphasis on projection domes than on fully-realized practical sets. That's not surprising for an enclosed Coaster, but then what is causing this budget to balloon towards $450 Million dollars??
