Steve, thanks for asking!

Obviously we won't get everything, but some great suggestions have been made.

Tyros X Module
Style libraries as add-ons: C&W, Latin, Bigband, Pop, Rock, etc. If you don't play it, don't buy it!
Improved Vocalizer:
Audio drums, and guitars,

Most important to me!
It's time for Yamaha, or someone, to move into the 21st century.
We need "talking keyboards" i.e. synthesized speech capabilities to read menus and help navigate the instrument.

I know for a fact that there are many blind and/or visually impaired musicians who would benefit greatly from this.

Sell it as an option, as has been suggested above. If you don't need it, don't buy it.

We've had talking watches, calculators, phones, elevators, scales, thermometers, and so on, for years. How hard can it be?

Thanks again!
Don P
