I'm doing a thread reread and how many times have we ended up talking about Potter? I think that says how impactful it is as an IP that no matter what, we kept coming back to it in discussions.
As it is, I do not believe Universal will clone any of the major Orlando rides, for any of the IP's. Mark Woodbury talked about attractions when he cited 'cannibalisation', not specific IP's. Which makes sense, why would you deliberately handicap your new Park's appeal if you have the freedom to use an IP that would do gangbusters? Especially when people will travel just to ride the latest and greatest rides, so by not cloning attractions but using the same IP you still have appeal but you reduce the cannibalisation aspect.
