Strongly disagree, a VR system would take way more maintenance than sculpting a beautiful themed environment and keeping it that way.
VR is new technology, it's experimental and whatever they add now will be out of date in several years time. Then consider that technology and roller coasters don't blend well. Take Blue Fire and Space Mountain / R'N'R at Disneyland Paris. If you've ever been on these rides multiple times you'd no doubt have noticed the onboard audio isn't very reliable, and Blue Fire's heart beat monitors are just as likely off then on. This technology isn't complex and the parks running them are world class but even so they are always breaking. Why? Because the PLC controlling them is a very delicate thing. Attach it to a Roller Coaster vibrating its way around many miles of track each day and you have a recipe for disaster.
As you can guess maintenance costs will be through the roof. Not to mentioned they'd need to hire a new team solely to repair them.
But lets consider that one park (Europa Park) is experimenting with this technology. If you watched the article about it on Click you'd have seen that on their first lap the VR failed to sync. Imagine if that happened all the time, which it will if not properly maintained. (Hint: the outcome is motion sickness...)
Having said all that this is just the type of gimmick I could see them latching onto. Personally I love Air, simply giving it the Theme it always deserved would be my ideal improvement.
