I think it is safe to assume that there will be a big drop in animatronics, which will be replaced by screen projections. Simply because this is the route Disney has gone with other rides in fairly recent history. So I think it's a fair assumption.
The question is whether this represents a decline in quality. I think that aspect is subjective.
FWIW, my take is that it doesn't necessarily have to mean this, so long as the ride is emotionally compelling. But I feel Disney has done "thrill" (quotes because they are bunny slope thrills, but that's what they're meant to be) / action rides much better than narrative based rides in the past decade and a half or so. I think rides like Soarin, Test Track, Flight of Passage, Slinky Dog Dash, Toy Story / Buzz Lightyear, Mine Train, Expedition Everest, and probably Dinosaur (haven't been on it) are great rides. Rides like Nemo, Little Mermaid, Runaway Railroad (have Youtubed but not ridden) and Frozen I would rank as more "ok" rides. (Pooh is something of an exception but I suspect that is because it was built on the preexisting structures of Mr. Toad.) Contrast that to the era when classics like Peter Pan, Pirates, Haunted Mansion, Small World, and Jungle Cruise came into being.
