I havent read the whole thread, but here's some info most people do not know. Property ownership and statisics are public record. For ex., search yahoo for osceola property appraiser. Then search the records for Disney. The WDW info will come up (interesting fact, the whole property is worth more than 300 billion dollars!) So if you know what county the theme park is being "built" search for Disney. If you get no response, then it's just rumor. If there was one in Texas, it will take away the appeal to DL as TX is fairly close to CA.
Also, before Disney builds anything they usually go to the press. They get most of their support from building and construction costs. So they would have needed to get sponsors. Not even Disney could pull sponsor's out of their behinds. Plus, why wouldn't the sponsor's mention it? Im not doubting those of you who claim to have seen a castle, but trust me, after WDW land was built WD went straight to the press and then started working on blueprints. Secretcy isnt like Disney. Also, who wants to attend a park noone has heard of until the opening, or right there before? Epcot was announced in beginning stages of planning, the MGM tower was built to anticipate guests, and AK was announced way before they went to Africa to harvest the trees and landscape they'd of needed for the animals. Very unlike Disney!
