Yes there is a PSR9000 pro keyboard coming out soon. It will feature the same 76 note keyboard found in the EX5 pro synth. I haven't seen pictures yet, but my Yamaha Rep saw it at the summer NAMM show and says it looks really cool. The estimated retail price is about $3800.00- $4000.00. The other keyboard you saw is a 76 note version of the low end Yamaha PSR keyboards. It will retail for around $399.00.
