Interesting discussions. A few points from the mess that is inside my Cranium
As of the start of the year, both CC and BW were still intact, the former deactivated and the latter close to the point of no return. Although the simulators used to be cycled to keep fluids running, recently this has stopped.
Wonders of Life returning in its original but updated form was one option looked at - it was below a proposed reuse and retheme of the pavilion. This option I believe was favourite. It makes sense - the infrastructure and structure are already built. The Geo dome is a massive showspace. The secondary show spaces can be reused quite easily, or just as easily removed from the Geo.
Imagaintion - plans are drawn for several scenarios. Which one happens depends on budget and timing. The favourite was one that would please a lot of people and possibly give FW a new E Ticket in the traditional sense. The attractions would make use of all available space, and again this facility is already built and able to handle more people than it does at the moment should the interior items be built to do so.
Energy - still lumbering on. A massive people eater when run at full capacity. I`ve not heard any firm plans to do anything major to the attraction yet, but given this and Imag regularly run at way below capacity and the fact that the Wonders Pavilion is easily able to make onstage again this is one third of FW that can easily and relatively cheaply be reconfigured to greatly boost guest capacity with no major new builds.
The price though.... $30m? Not a chance. It cost the MK somewhere around $25m to convert AE into SGE. Aside from 2 new A-100s that work was mainly cosmetic and superficial. To reconfigure any of the above 3 pavilions into something less than embarrassing would cost at least double that. And believe me, Burbank, Glendale and even Orlando know they can`t repeat Imagination again, let alone Test Track.
