I'm kind of wondering if some these aren't being touched up to as they might have plans to redo them more extensively after Epic. River Adventure I could see change into the new Jurassic World version from Hollywood. The land as a whole has seemed to slowly be transition to Jurassic World with the newer additions like Raptor Encounter and Velocicoaster.
Cat in the Hat really needs some love as well and a big overhaul. It's a cute fun ride so would hate to see it go but it's a shell of its original self too.
What would an overhaul to The Cat look like? I think it operates much like it did back in the day aside from the spinning, which was been adjusted many times over the years (even stopped for a while). There's no chance of it returning to its original intensity, when it had the most G-forces of any ride in the park.
