If "They" feel stuck giving guests what they want... and yet still unsure how to update it for the future.... then oh boy, do we need to have a cleaning of the house at a few dept's.... this isn't hard people, it's really not hard.
The original could have been updated, with the projection tech used on the castle (think that "white room" with pixel mapped images all over it" The turn table scene updated with new AA's, new background video (led screen?) and more animation / movement (think robot arm) take out the science section, replace that and the ending section and that would do the job. Easily bring it under 50 million to do.
Even having to rip out the trash that is there now, restore the track, rebuild a few "key" scene's with updated tech, again.. not hard... and there is plenty of skilled and passionate people around WDW who'd be able to lead the charge on it, if they were just unshackled and given the creative freedom.
