Sorry, but this is far from reality. Yes, there are cuts on the way--and yes, there are some seasonal changes on the table, but none are as drastic as you have made them out to be.
WDI has not cut any projects already under preparation or work (meaning Space Mountain, Hall of Presidents and Stitch's Dance Party [or whatever it is called] are still a go) and there are plenty of projects still awaiting the green light. Star Tours specifically is still happening. ILM, Lucasfilm and WDI are too far into production to put the project on hold. If anything, the opening will be delayed, but the fact is that Tokyo's (and eventually Shanghai's) Tomorrowland(s) will be using the new film as a staple in their opening(s)--meaning that these resorts are driving the progress of the new film, regardless of the economic conditions here in the United States. The worst case scenario for that project is that the film won't be stateside first...
Much like Universal and Seaworld, Disney is keeping the projects necessary to keep attendance up while it holds others that were lesser in necessity. They need the newer attractions to couple with their many campaigns for lessened prices and deals.
The World Showcase won't likely see a later opening time as a whole, though the American Adventure may have its earliest show cut out to decrease some extra costs. Some pavilions may have staggered openings but not by more than a half hour at most. With Kim Possible now in the World Showcase, they are locked in for lengthier hours in the daytime, as the experience was not designed to operate past sunset.
Animal Kingdom management is not prepared (or willing) to relinquish its newly claimed "full-day" status, regardless of the economy. Animal Kingdom will not drop hours anytime soon (except for a possible 5:00 pm closing on some weekdays).
Some resorts have been targeted for potentially staggered closings but none will be shut down for more than a period of a few months at a time. The goal is to keep all of the resorts active for as much time as possible so as to allow them to remain conditioned for full service when the economy picks back up (whenever that may be).
In regards to those two major members of WDI leaving, there have been talks but they have been nothing more than talks. And truth-be-told, both members in question have been considering leaving on their own accord for quite some time. If they leave, it will be a loss, but it won't be the end of Disney or of WDI.
Personally, until any piece of this "news" goes live officially, I take it with much salt. If there has been anyone able to withstand economic strife, it is Disney, and they will do what they have always done to adjust to the times. While I mean no offense in my response, I personally feel that the OP may be overacting; claiming Armageddon at the hands of two executives taking the brunt of the blame for a set of decisions that run far higher than them. Economic situations can only get worse with signs of alarm and panic such as these, so rather than freaking at the first sign of proactive motion within the parks, we must take the time to look at the issues on a more in depth, informed manner to find that what is going on is a progressive movement by the company to protect itself and the integrity of its parks. So again, I say that this original claim isn't "reality," rather a set of negative rumors based around more positive information.
Look at these protective actions as a sign of wise decision and company strength--not as weakness or impending doom. Though cuts may seem sad, they are made to protect the "larger picture," and in this situation, that is a good thing.
