Where have you been lol. Themeparkinsider had the exclusive on NYE. He even has a little art work.
What was posted on that site is far from offical, or even unoffical. He even says himself:
"First, these are labeled "Concept," and dated last month (November 2011). There's no sign that these plans have been revised, or approved by engineers, so I am assuming that they are initial concept plans. Even though they are quite detailed, they are far from final, and anyone who's been involved in attraction development can tell you that much can change in the development process."
Just because he got to see concept art does not make anything offical. I am sure Universal has a whole room full of concept art that will never become of anything. He was simply shown some drawings of something that Universal might do. I find it hard to believe that they would close Jaws so suddenly because of some unapproved by engineering concept drawings.
Also, if this was really true, Universal would have had him pull everything from the site. Like he said:
"Third, every page is stamped "Confidential," so I'm not supposed to be looking at them or telling you about them, and I'm certainly not going to tell you where I got access to them, so don't even bother asking."
Leaking CONFIDENTAIL items like that could cause some serious actions against him and the person that showed him the concepts. The fact that Universal has done nothing makes me think that either he is way off on their plans for a phase 2, or a phase 2 is still to far along to even take any action because so much might change.
Sure, I would love a phase 2 of Potter, but you can't take this one article on this site to be an unoffical announcement.
