Why should Yamaha use the brand " SX900 " ?
Already in use for other products. See internet.
It sounds natural they will continue PSR - xxxx.
Why should Yamaha go for 76 keys ?
No way ... 61 keys will be continued. Why not ?
Why not built-in speakers, as usual ?
Why a touch screen ? Too expensive, I guess.
Why blue Genos push buttons ? No way.
