I wonder if the natives (locals) will get restless if they put in the waterpark expansion next year instead of going with a thrill ride? The changes the park has made over the past 6 or so years have all been well needed and has really made the park a lot nicer (brick paver walkways for a good portion of the park, new signage, repainting a lot of various building etc) and they've done a lot to make the park more family friendly after a decent five year run from 2003 to 2007 where 4 of the 5 years the park was adding to their thrill ride line up (Steel Venom, RipTide, Xtreme Swing, Skyscraper and Renegade). Tragically for the park though, RipTide's arrival didn't/doesn't generate a lot of enthusiasm after the first season, SkyScraper has since been relocated to Cedar Point, and Xtreme Swing, while well received, has had some off and on mechanical issues that has affected it's ability to stay open. So they've had some mixed results with a pretty good amount of investment that went into the park during this span (about $25 million). So I think for someone from the area it didn't feel like the constant stream of awesome that was intended.
Does the water park need some new attractions to put it up to par with other regional water parks? Absolutely. However, is the park due for a mid sized to large thrill ride as well? I think so. Would a new coaster be freaking awesome? Most certainly.
