Let's not forget when Walt first built Disneyland, no one ever heard of Anaheim. In the early 50's it was still a relatviely small farming community.
Same goes for Orlando.
I'd say it's just the Disneyland Texas rumor returning once again like its zombie self. A new park announcement seems better suited for some big event. With the internet I also find it hard to believe nobody saw it happening. Unless Disney was stupid enough to not buy the land first like with Disneyland's Disney Decade expansion.
