I'm not sure what the plans for Congo Falls. Have you seen the roof though of the station? It needs to be replaced pretty bad.
PKD got rid of Diamond Falls which opened in 1985 a few years ago. Not sure if PKI will get rid of Congo Falls or not, it harldy ever has a line, but on hot days alot of people do ride it. Congo Falls AKA Amazon Falls opened in 1988 so it is 18 years old now.
