^If they can do more themeing to X, Scream, Colossus, and Goliath....that would make it even better. I say give Scream at least some grass and trees and re name Scream! and give it new colors. Also, they need to close revolution for a little and get some workers in their to get all the rust off of the ride and fully re-paint it.
I have no idea what they will do with the empy space. I always thought that SFMM never needed a water park. But, it's a good way to make money I guess. After they get the 10 mil back from what was spent on X2, they need to spent a lot on themeing and getting Revolution back off of the ground. So far, they have made some every good decisions on fixing the park up, so theming those rides maybe a reality.
