I know this is way off topic, but if F&F is taking over part of the Simpsons Fast Food Blvd area, what if Bourne took over the ride space a few years later? That would be very costly, but both could fit together as an Action movie theme land, if that's what they're going for with F&F. Right now the big draw is the Simpsons Ride building next to the Starway, but with a coaster next to it, it seems like the bright colors would clash. A purpose-built Bourne theater in the same space could blend in better and provide a little more continuity.
Maybe I'm being ignorant here, I really don't know. USH has so few things on the Upper Lot that hasn't really been touched in the Comcast era, and The Simpsons Ride is one of them. And it would also give them a reason to re-develop the Waterworld area a few years after that for a new land, with having two stunt shows in the same park, if that's really going to be set aside for future park developments.
