Yeah, but I see a couple of problems there:
A. Neither Rougarou nor Centurion would have anything to do with any of the themes (and Centurion might not ever be built)
B. Even though the Shockwave is a piece of Togo crap, it's still a roller coaster, and going from 14 to 13 can damage the park's image as a local thrill capital, especially as Busch Gardens down the road moves up to 7 with Diavolo.
Personally, I say eradicate the Grizzly, replace it with a WMG, add slides and general improvements in 2016, then in '17 add a big coaster at the Hypersonic location.
