Dnj, it's based on the PA-500. I think it's a great move for Korg, but IMO the upgraded piano sample, 88 keys, stand and pedal don't add up to an $1,100 price difference. Perhaps Korg set the price high as there is no competition (currently) for this unit. The Yammie MM8, and YPG series can't even compare to the 588.

Yamaha is essentially doing the same thing. The MM8 has absolutely no new feature updates, Yammie didn't fix the MANY reported problems by users, yet they released a board that in no way was supported by a huge volume of requests. Then they charge $400 more just because it has 88 gh keys (not even Yamaha's top action either-supposed to be YPG keybed).
