When I went on Sunday, the ride was top-notch, and I didn't feel anything wrong with it, so I guess Sea World is trying to be careful with this ride because, like you said, Obi Ubamba, this is currently the TM attraction at Sea World. I love this ride, and so do many, many others, so Sea World is going to keep this one in top shape.
My only irks right now with Sea World are Kraken and Journey to Atlantis. Both are in less than acceptable condition, and Kraken needs a huge refurb to add some dark ride elements because whatever little theming is has doesn't make up the fact that it can be compared to a Six Flags roller coaster. JTA just needs some love with a refurb that updates the story and the effects. If both things were done, Sea World could market their new and updated rides, and end up gaining more.
