There is nothing new to report. As we've discussed in other threads, the site will be dormant until they get a buyer (which is unlikely in this economic climate and at that location), or they build the highway extension (which probably won't happen inside of this decade at the earliest).
What's left on the site is Roaring Falls and Accelerator (S&S double shot). The Orbiter (flying carpet) might still be there as well, I can't remember.
The site is kept from falling into complete disrepair by Herschend, but they aren't going to do much other than keep it from being an eyesore. I could see OzCat being knocked down in a few years when the wood gets really warped. It's already starting to look bad just because of the handrails.
