I think stories like this - eg "Disney is getting ready to build something" make the rounds every so often. I think part of that is tied to the way Disney built WDW, or at least bought up the Orlando area property through a maze of shell companies until a reporter started paying attention. You'd love to be the next outlet that caught Disney doing anything remotely similar.
That said, I remember stories rumbling when I was a kid that Disney wanted to build in the midwest, and was looking "seriously" at property in southern Oklahoma due to its close proximity to both I-40 and I-35, but it was just legend. Not saying this is necessarily the same thing, but color me skeptical.
