well they confirmed several things...
exact same ride layout...
removal of all testing theme, replaced by design theme...
pretty much said the major ride aspects are not changing at all (handling, environment, speed, etc)
Sounds like the major show scenes are just being rethemed and redressed... a new queue, pre and post shows. Probably some other lesser tidbits along the way.. but it sounds like the onride experience isn't going to change physically at all. Just what you are looking at and hearing..
Sounds a lot like SSE redo..
