Here's an 'official' site
http://www.disneyland-cyprus.com/ Which doesn't look very official to me. Shouldn't there be something from Disney themselves? Also each link at the side you click for more info (example. Florida Disney) loads something completely unrelated.
It's stupid to plan something you might not even get permission for. Most of the tourists will come from the Turkish side, unless the Greeks manage to make great offers, Turkish side is cheaper and as someone mentioned they have stuff such as casinos!
I've been to the Disneyland in France and I really don't see how they can fit such a huge park here and where will all the jobs come from? More Europeans invading Cyprus?
