In the end I rather have 2 excellent parks then 4 where the good rides are sprinkled around those 4 and the rest is mediocre at best.
And Comcast is really at it plussing Simpsons, Spiderman and now Hulk. Replacing old and expensive to repair rides with new ones like Potter in Mythical and Jaws. Adding rides where never (or a long time) was noting like Hogwarts Castle, Simpsons Spinner, Transformer, the Hogwarts Express and the Raptor meet and greet.
Kong filling up an empty plot and F&F replacing a old show and ride to add popular ip's into the park. Avangers could be added behind the shot towers and I'm sure they are thinking about expanding Suess and replacing Mythical and Newspaper cartoon land.
What we have heard from Jimmy Fallon will at least add some more theming to the New York area and Nintendo will add enormous foot traffic to the almost dead Kidszone area. Hello Kitty will generate more traffic then Lucy and the list goes on.
