SplitFish's website describes the glideFX as "the world's first B-type Controller. glideFX uses a 'Trackball' to manage movement that is normally controlled by the right analog stick. Separate left right controls and adjustable Sensitivity settings." The site reports the glideFX controller is "for the PlayStation 2" while some emails have stated it's the "new PS2/3 SplitFish controller" that "is to be shown at E3 this year." Probably means this same controller will be updated to be PS3 compatible, with wireless functionality and whatever else that entails.
