Don’t know about arrangers, but Roland has announced a hardware and software upgrade to the Atelier range, (Which sales wise just continues to go from strength to strength) however it will be interesting to see if it can be retro fitted (At a cost) like in the previous range. (The US really lost out the last time, as Roland US and the dealers (Unlike other parts of the world) refused to do the upgrade, and you could only get it by trading in your old Atelier for a new one)

Korg may bring out the PA2x with 61 notes and internal speakers, just like they did with the previous PA1x Pro, PA1x range. (It seems strange that they haven’t already followed the formula that worked well with the last range)
