I agree that Donny's assessment is pretty pessimistic.

It will have a lot of new voices. It will have over 100 more onboard styles - over 400 compared to 300. It will have the better speaker system. And it will have the audio drum feature, the more realistic guitars plus amp distortion.

I'll be happy if all of the T4 styles that I have sound good on this keyboard because some of them don't sound quite right on the PSR-S910.

There are probably some features we haven't heard about yet.

When I look at the button configuration, I see approximately 10 extra buttons on the right side. Maybe I'm wrong.

It would have been nice to get a larger touch screen or the ability to operate buttons and sliders with a tablet. Since I mostly want to make music instead of operating a fun gizmo, this isn't a deal breaker for me.
