I've been on the mindset that if anything is happening to the Studio Tour in the near future; it'd be a change-up to have it be oriented into a Warner Bros. Studio Tour like experience. Something that focuses rather than to stimulate the feeling of "Films being simulated" to a grander version of the VIP experience's Studio Tour. Something that has active museums that rotate props, costumes, and picture cars; to match that of NBCUniversal products being developed.
Continue going through the backlot and front lot, by personalized trolleys, that can specifically tailor for per group tastes and preferences; while saving spending costs from simulated sequences (perhaps with the exclusion being Kong 360, as I could see them toying around and redoing that).
I think the Studio Tour has value for USH. But not as part of the current lineup.
