Thing is, there is considerable overlap between arrangers and WS's with chord following arpeggiators, these days. Even my venerable K2500 can do some fairly simple chord following, and modern WS's have MUCH better chord recognition.

It is difficult to imagine Kurzweil moving into a market that is shrinking the way arrangers are, nowadays. The younger demographic, which Kurzweil have always addressed, are far more synth and arp obsessed than into arrangers... But maybe Kurzweil, if they choose to go down this path, might be the first to address the needs of the young as well as the elderly players. I still think the idea of combining styles (with NTT's rather than simple note usage) with chord following arpeggiators like the MotifXF and synth control knobs might tempt the younger players back to the segment...
