Basically, these appears to be the rack version of the JP8000, with a few extra goodies. It is a 6U rack piece (big!) that keeps the RPS and arpeggiator of the keyboard version, but adds: filter inputs galore (with a Vocal Modualtor Morpher), 40 knobs, a new storage system called SmartMedia, even fatter sounds than the Jp-8000, multi-effects, and a unison function. Very impressive specs, that's for sure, to say the least. They are very new, so the word's not quite out, but I'm sure they're rad as all get out.
