I see this as a good sign that management decided that Action Zone should be prioritized over The Vortex plot which I strongly believe was the correct decision.
Action Zone is the ugliest area of the park with little shade and no discernable theme.
There is no balance to the ride lineup in the area. Everything there —outside of Congo Falls— could be considered on the thrill side.
The rides in Action Zone are quite old and won't be around forever so replacements will need to move in. The eleven-year-old Banshee is the most recent attraction.
Action Zone is a ton of land with relatively few attractions, and only one marque attraction.
I seriously doubt Skyflyer netted much if any money in its final years.
The Vortex plot will be addressed after AZ at some point, but that area of Coney/Rivertown is in much better shape overall than AZ.
