Thankfully, yes, I've heard this show is closed. I'm sorry you liked it, but to some people it was far too loud and boring to enjoy. I hope they find something good to put in its place. Sorry, but if I want to see a bunch of skating or roller-blading, I'll find the nearest empty parking lot where teenagers hang out.
When a truly awesome and imaginative show (Festival of the Lion King) is in the same park, I'm sorry, but it's hard to justify keeping this one running. FotLK raised the bar pretty high, and Tarzan just limboed right under that bar. It's too bad, because a theme like Tarzan deserved a better show than the cheesy pseudo-rock they played and a bunch of skating monkeys.
