The weird thing is that I'm moderately certain everything that closed in 2016 is still intact. Sum Of All Thrills is still there and clearly visible from the Colortopia area. Pretty much nothing has happened to it since it closed:

I wouldn't be surprised if StormStruck was still around as well. Colortopia and the Nanooze area are still there and functioning, and the VISION House is used for passholder merchandise during events. It's weird just how much they aren't doing anything.
