Of the Yamahas, this is closest to the PSR9000 in niche, weight, and probably price, which I guess will be about $4K retail. It will probably be sold through Roland's Musical Instrument division rather than the Pro division, so discounts will be hard to come by. My guess is that the weight is due to the speakers. The PSR9000 was about 10lbs heavier than the PSR8000 largely due to the use of wood in the upgraded speakers.
