So I asked over on Magic if they plan on using VQ for MMRR or not and this is the answer I got from @Magic Feather and @Marni1971MMRR also doesn't have an elevator and simulator drop tower either. I think Disney wants some big queues for once.
Originally no, however I have recently heard it tossed around.
I’ve heard it mentioned for all forthcoming major attractions. Must be the current buzzword in TDO Towers.
Not a surprise considering the three major attractions opening/having recently opened (RotR, MMRR, Rat) all have abysmally small queues. If the Hagrid's queue is a marathon, than these queues are a RunDisney Kids Race.
So, not saying it IS happening for future attractions, but it's certainly being talked about. By the time MMRR opens, they'll have learned from Rise, so a VQ system should be more organized and less chaotic if it happens.
