Just a blue sky/hypothetical thought...
I believe it's very possible that Comcast's long term goal/vision for Universal Orlando is to "have what Disney has". That is to say, I think they're trying to match the number of dry parks, water parks, and possibly hotels. It's a long way to go obviously and a lot could get in the way (eg global/local economy, company finances, land/rights issues, etc).
If true, Disney's goal would be "stay one step ahead." With that in mind, we could see a theme park expansion war.
Maybe not as large as the first major Orlando theme park war (from 1989 to 2000), but all indications show it's at least
possible. Debatable on if it's
likely, but at least a non-zero chance.
[Adding this thought here as opposed to the other thread (Universal Orlando Resort Expansion (Part 2)).]
