PF leaving would be a huge loss. Universal is trying to become a resort destination, and pull more family vacationers to Universal instead of Disney. This means a lot of first timers to the park. The only reason we don't mind it leaving that much is because we've done it multiple times, and it doesn't have the lasting effect something like FJ or Spiderman does. But PF has makes a huge first impression. It's an attraction that somewhat interacts with guests, people find it really funny (including myself), and it has a huge wow factor to it (facade, water vortex, falling wall at the end). To be hones, I'd rather stare at that facade then Hogwarts. There's so many small, incredible details to it, it's just beautiful. Universal needs these big impressions for the first time visitors, to really wow them, and to add to all this FJ is not a typical attraction, which is even more of a bonus. Universal needs these big first impressions everywhere, while being a well rounded park.
