POTC will never ever come to the states in the way it was in Shanghai. Shanghai historically used to be a pirate port and where the term Shanghai'ied (the practice of kidnapping people to serve as sailors by coercive techniques such as trickery, intimidation, or violence) came into existence. It has cultural value that wouldn't be appreciated elsewhere. It make sense why Disney would make it perhaps the most expensive and impressive ride there from what we have seen so far.
Secondly, been to China, have fun getting a visa, dealing with air pollution the first day and lastly not having your cell phone or laptop unless you want it to be bugged and all your information given to the Chinese government.
