I'm sure Imagineering would just love to have installed onboard audio with new visual effects, and the works, but they weren't given a budget big enough to do that. For what they were given with the off-board ride audio, it seems like they did an okay job. At this point I'd rather have off-board audio than none at all. :shrug:
Not saying this is always the case, but talk to people who have worked for WDI, they have a tendency to not be the most efficient with funds. People here always blame management, and WDI are viewed as gods. It's not always true. Yes there are bad imagineers.
