Speaking from my own opinion only, I think it’s time for a new coaster! It has already been five years since the last brand new coaster was erected upon these Ozark hills, and it will be even longer before a new one is finally built, and operational.
Family rides are great, and I believe with the River Blast, and especially with The Grand Exposition, the needs for a new family ride have been met for a while.
Additionally, I think the park's quota for new thrill seeking stationary ride has already been met with The Giant Swing.
So here is my vote for a new coaster!
However, I am actually not picky about the type of coaster. It can been an indoor, or outdoor coaster. A wooden coaster would be nice, but that too is not a requirement in my book. As long as the theme is adequately there, then I am all for it. Sorry, this is more of a want rather than a prediction.
