You asked!!!

Do something about the worst key feel on the market...that includes the cheapest keyboard controllers too!!!!

Start listening to what players want...76 keys (if you improve the feel and make them "full" size)..
Improve the harmonizer...Yamaha has had enough time (repackaged) to do something with their vocal harmonizer..

Improve the over-all quality (construction)..and maybe it won't come across as a toy...so much!!!!

At $1,500..there is plenty of profit margin to take some cheapness out of this series...and make it a better product..
