It may be fair to bring up that quite a few of the dinosaurs are gone, badly in shape, and with various effects either turned off or not working as it should.
It's hilarious to see how bad the shape of the attraction is now, and that I completely agree with everything said.
My thoughts for screens, is that I only see them in the Indoor Portion, and if they are, it won't be traditional screens and will require the building to be gutted to accommodate changes.
I do think the T-Rex at the end is staying, but a part of me wouldn't be shocked if the T-Rex surprises you from the side, as the I-Rex takes over the T-Rex's spot.
As for the Mosasaurus, if it's outside, I can only see it practical. The only way I can see it indoors, is if they are enclosing the ride from the point to Stegosaurus Springs to the second lift, but I don't see that at all.
