With all this talk of potential closure dates... Obviously there are no guarantees until Disney says something, but insiders: is there a chance Dinosaur might still be open in early 2025? Like, Jan-Feb? Was thinking of making one last one-last-trip; don't wanna buy tickets and book flights/hotel only to find out "surprise, it's closing January 2".
Leapfrogging off this post: I think people are assuming it's gonna end up being a clone of DL/TDS, but given there are apparently aspects of the way the ride is built that would make a "mirror" 1:1 clone impossible, I don't think it will be. The story is different enough that it wouldn't make entirely too much sense to be the same. There's not going to be one big room in the center, for instance, that's closed off in Dinosaur's architecture IIRC.
That said, I would be very surprised if there isn't some boulder reference at some point. If it's not replacing the static jump-scare Carnotaurus, there'll be a screen with Indy running from one while you run into whatever the mythical creature ends up being. I know your post is more about the quality of effects Disney might put in (projections/screens vs. practical), but, I'm just spitballing ideas here.
One thing I wonder... to further differentiate the two rides, is it possible to like, take the ride cars and turn them around? Then it would technically be the same track, but mirrored AND reversed.
