Aren't we all forgetting that Universal asked people about a phase 2 in recent surveys? That proves definitively that they are at least considering it.
What about the millions of people that are/will be coming to Universal just because of Potter? While they may enjoy the rest of the park, they will wish to spend more time in the Wizarding World, or wish that it wasn't so crowded. Not to mention repeat visitors who need a little extra incentive to spend another vacation at UO. Universal would greatly satisfy these people with an expansion, and if recent reports are anything to go by it is the Potter fans that Uni is most anxious to please right now.
There is nothing stopping them from planning an expansion (which even if they decided to do it tomorrow, wouldn't be built for likely 2-3 years) and touching up the rest of the park in the meantime. Anyway we all know the only reason that Universal would even consider a park-wide "refurbishment" is because of the new customers Potter is bringing in. That shows just how "Potter-centric" the current feeling of the resort is.
On the future of LC I agree with Frogki - it's going. What's the point in keeping it around? It was a good idea, but the attractions there now are mediocre at best (widespread opinion) and they are original, which, while that may appeal to us theme park fans, is not going to sell a lot of merchandise or get a ton of people's interest. There is no way Universal is going to spend millions of dollars adding a major new attraction to LC or some other land when that is simply not where the money's at. What kind of return are they going to get by spending money on LC, compared to an expansion of Potter? And they are a company which means first and foremost they care about making money.
IMO we can expect the park to be touched up generally in the next year or so, some new effects added here and there, then a moderate to major expansion of Potter in 3-4 years, then a major expansion to a different land.
This. I totally agree, thank you lol...
