As far as Al Lutz, I have to say he generally seems to have a lot of reliable inside information. He has been first to report on a lot of the changes at DCA, DL's 50th as well as the TSI refurb project in the works with surprising accuracy. But it should be considered that he reports on what's being considered in the corporate offices, and as we all know, a lot of great projects that almost get greenlit often never come to pass.
As for the Magic Kingdom, it's absolutely my favorite park and I love it to death, but I personally feel updates and refurbishments have been a long time coming and should have been implemented long ago. Disney boasts about record profits and increases in attendence, it's time their flagship park started feeling some of the love. Call me a rabid fanboy, but I think it's long overdue.
