My guess is they'll keep beefing up the current resort, add another new hotel after Sapphire and the water park, then we'll mysteriously start to see work on the Lockheed site, but long before anything's announced.
Eventually we could find we have Universal North and Universal South, linked by bus transport, with South housing an extra park, a load of hotels, and a timeshare resort.
Backing onto the Convention Center, they would be in prime position to catch a lot of the Convention Center crowds who currently fill Pointe Orlando and are driving the I-Drive expansion. Now what do Convention-goers like to do at night? How about a Pleasure... I mean 'CityWalk 2' nightclub complex?
Can you imagine if all this came to pass? A fully built out North resort, then South resort with a new park, great hotels and nightclub district and all connected to I-Drive and the Convention Center.
I wonder how Disney would respond if all that happened?
