While I agree that new things will be coming to AK, your timing is way off, jt. They would have to break ground NOW if they wanted to be open for the 40th. And FotLK isn't planned to be closed anytime soon as far as I know.
I would be suprised if it ever closed. Become a parade again while awaiting a new theater however........
And I think they could build a 20K attraction (phase 1) by October 1st 2011 if they wanted to. That is over two years from now.
