I will be brutally honest but I can not wait until they get rid of Colossus. Its not friendly one bit. When the tiime comes to replacing it, I sort of hope they look backwards instead of forwards with regards to it. I would love them to revisit the original plans for the area
They could tweak the design to fit and just give us something a bit more dramatic now that the power of ten has been duplicated in other parks.
As for theme, I like the Lost City theme, so it should stay. I would sort of love it if X was to be removed from inside the pyramid and then have the pyramid as the station for it, so you come out of the pyramid. That would be kind of cool.
