JTA has looked pretty much the exact same for the past 10 years. The only things that today's version is missing are:
1. The video of the man in the window right after the load station. (Wow, this was such a convincing effect, I'm going to miss it so much)
2. The statue turned medusa.
3. The medusa head going up the first lift.
If you really think the park should prioritize those effects over a new rapids ride - then I don't know what to tell you, honestly. There's nothing nostalgic about any of the listed effects above that would make SeaWorld want to preserve it as if it's Small World or Peter Pan's Flight.
Not quite sure why this is even a topic. Let SeaWorld blow your mind next year with what should be their best attraction since Manta and lets all move forward into the future.
