Here's some information and an artist rendering courtesy of Screamscape.com. They have the name of the attraction listed as "Crush 'N' Gusher".
Disney announced at last their Master Blaster waterslide project that will open in Spring 2005. The new slide will be part of Hideaway Bay, a whole new themed area of the park. They describe the new attraction as a combination of steep drops and gravity defying coaster-like inclines where you are powered uphill by water jets. Riders will travel through what appears to be a rusted out tropical fruit facility, weaving the rides through the wreckage of the fruit plants old wash facilities. There will be three different fruit spillways to choose from: Banana Blaster, Coconut Crusher and Pineapple Plunger.
