Here's a paragraph on the wave of investment Comcast is making at Universal Studios, which it owns.  "Mr. Woobury" runs Universal Creative, and is responsible for their Harry Potter success.  The new water park will be on the site of Wet 'n Wild:

Now Comcast is speeding ahead - a Harry Potter expansion, featuring a working Hogwarts Express train, opened in 2014 - in large part because of Mr. Burke's confidence in Mr. Woodbury. To create the new water park, Volcano Bay, Mr. Woodbury said he sent his team on a round-the-world tour of existing water parks. "We want to build something that is totally groundbreaking," he said. "What's the state of the art and how can we surpass that?" 

Of course there won't be a surfable wave pool, but at least we know they're trying to make it interesting.
