Even if that were true (I don't think it is!), since when has having a "better" version of something in another park stopped Universal from doing something before? Transformers and Supercharged are inferior versions of attractions in IOA, and those aren't going anywhere anytime soon.
Let's hope they do have bigger plans for USF, because this and KidZone feel like half-measures to fill time while waiting for EU to open and additional resources to be freed-up.
