1)61key FSX and 76 key weighted key options

2)Audio loops in the styles. Atleast some of the arp stuff similar to the Motif

3)Software to easily and quickly create Yamaha Style accompaniments using audio loops(a la Garage Band which uses pattern based approach in creating songs by combining various audio loops.)

4)Tiltable touchscreen. Possibly responsive to both touch and existing non screen button presses would be nice... Just incase one of the two fails

5)More and lots more of the Yamaha premium content from musicsoft to customize and keep keyboard contents up to date.
