For all intents and purposes it's now a discontinued model. Casio shows it as current and appears to be holding the line on price (at least in the US) until the remaining stock is depleted. Meanwhile they have shifted their development resources to the CT-X series, which is downmarket in features and a lower price point, but has the newer AIX sound engine.

Casio tried to crack the MOTL arranger market with this board and failed. Price was too high, the quality and reputation just aren't there vs. established players. And young people who might be intrigued by the pads and sound editing don't have $1100 to spend.

A few features are missing from the venerable MZ-2000, but it's easily the best Casio arranger in ~16 years. The multipad implementation is extremely flexible. Pads can be used for one-hit, phrases, or even to trigger chord progressions that temporarily take over arranger control. Clear touch screen, in-depth sound editing, full sequencer with separate chord track, note-to-arranger, organ drawbars. There's a string quartet style that (combined with sync stop- the first recent Casio to have this) is almost like a Yamaha Free Play style. Very complete feature set.

Where it falls down is sound quality, and the keybed is rubbish. Same clunky, wobbly keys used on lower-end models that you often see broken in music store displays. Anyone who test-played one probably would have looked at the price and left it on the shelf.

The MIDI implementation is also limited compared to the big 3. It probably won't get another OS update and that's a shame. If the MIDI implementation were better it could be used as a module and combined with a decent-quality master keyboard. Better sound could be obtained by MIDI'ing to a Ketron SD2, etc. It wasn't popular, and I'm guessing that's the end of Casio's strategy to move upmarket.
