As I mentioned in the referenced thread, I'm pretty confident that Disney is world-class enough to find an excellent way of capitalizing on their technology in such a way that it increases profitability. Sure some customers may be unhappy with whatever changes they decide to apply, but I bet most will not even know the difference, and many that will benefit will be positively effected by the advantages.
I can remember such prediction about the initial introduction of FastPass itself, about the first value resort (and there probably were such predictions about the first moderate resort, but I can't remember that specifically), about the replacement of Mr. Toad's Wild Ride, about the introduction of the Rock 'n' Roller Coaster, and so on. One day, when I'm really bored, maybe I'll peruse the Google archives for such predictions that didn't pan out -- nice way to kill a few hours.
The point is that no one is going to tell me that I cannot be sad about something I enjoy changing or closing, but that's about the extent of anyone's personal preferences. Over and over again its been clearly demonstrated that what we like doesn't map to what drives our purchasing decisions, and therefore the predicted unfortunate events never materialize.
