At least as far as the ride in Japan goes, they are going to be quite boxed-in by the existing Spider-Man infrastructure. They're not building from scratch, so whatever "physical" stuff they may be planning will probably have to be limited by design, as there's just not much room for any big show scenes beyond what's already accounted for in Spider-Man.
Now, USF's will almost certainly be a new build (I don't see how they could possibly retrofit the BTTF/Simpsons building to accommodate anything similar to what Japan is getting), so I guess the hope is that it would be a majorly plussed version of Japan's ride. And hopefully that plussing would include more elaborate sets and physical figures/AAs.
That's me trying to be optimistic!
