Yea, I don't know what all the handwringing is about. Nearly every ride or land that is cloned is improved in one way or another. Our Kong, USH's Springfield/Despicable Me, etc. The only thing I can think of that wasn't significantly improved was USF's Transformers, and even that has a better exterior (albeit not by much).
The word is San Fran will be flattened for this. All of San Fran. If that's the case, they have big plans.
