Roland has everything in their home to make a perfect arranger...

- the keybed of the RD2000 with aftertouch
- the sound engine of the jupier 80 (10 sounds assignable to keyboard)
- all the sounds (pcm and super natural) of the integra 7
- an option to load acb sounds into slots..
- an upgrade to their ea7 arranger style engine.. maybe even somthing like ketron’s launchpad ..
- nice big color touchscreen, or two normal size color touch screens.(i love 2 touchscreens with 9 sliders/knobs/buttons in the middle as in the ea7)
- sliders, knobs and pads
- full masterkeyboard functions
- audio over USB.
- organ sounds from the attelier range
- V-piano sounds from the rd2000

I think Roland could blow everyone away, if they wanted to..
If done right they can cater to both the professional workstation market as the pro arranger market with a single instrument
