I would have loved Tokyo to replace San Francisco because it'd give the park some nice variety while still being cohesive. You'd have Hollywood and Production Central, which make okay sense in Universal Studios, plus three of the world's biggest cities with New York, Tokyo, and London, and then Springfield which is a satiric take on middle American cities. Not that San Francisco breaks this, but it's just another American city. Tokyo would stick to this general theme while giving some variety in architecture, dining, shopping, etc. Besides that, World Expo and KidZone are the only ones that stick out, and those are likely not long for this world anyway. (Although KidZone is being replaced by SNW... a part of me still feels like it stands out like a sore thumb in USF. I give it a pass because they don't have much space, although part of me still wouldn't mind if it's in Park 3 just because of cohesiveness. But that's an aside for another thread.)
