I don't mind some clones but it would be nice to have some unique things to draw you to those parks. Hong Kong wanted exclusivity on certain things for a reason. I know people go to WDW anyway, they don't "need" unique draws, but I still think certain things should be unique. I wasn't a fan of hearing they wanted to clone Everest for Shanghai. I hope Zootopia takes that spot in Shanghai, LOL
Part of what makes Disneyland special (besides, you know, it being Walt's park) is that the Matterhorn is unique (although technically our Space Mountain is the same), they still have the subs, they have Alice in Wonderland, Mr. Toad ... are they "draws"? Probably not but it matters, at least in my mind, to have unique things no one else does.
