This. If the T-Rex jaw is still not fixed it's likely because they're waiting on parts and not because they're just ignoring it outright. That said, I'd like to imagine at least some of the broken effects will be fixed between now and Dominion opening.
The cost of a full revamp of the ride on the scale that Hollywood got is rumored to be similar in cost to the entire Velocicoaster expansion so I still think IF it gets a JW treatment it will be smaller in scope. Updated boats, signage, refurbished dinos, and one new dino at the climax. I'd still prefer if they just kept it JP, updated the existing animatronics and keeping everything else pretty much the same.
