Highly unlikely, Fran, IMO. Computer technology takes MUCH longer to trickle down to arranger users. Remember using CF Cards on the G70? After SD had basically taken over? Or SCSI long after EIDE became the norm? And where is Firewire? The universally used connection is next to impossible to find on a hardware arranger.

By the time the Big3 gear up to use an interface, it's time is long gone! Heck, arrangers with samplers (and even WS's with samplers) are loading up samples into RAM at speeds that were surpassed in computers well over a decade ago (even my K2500 beats most modern WS's!). They use off the shelf componentry for data I/O, and those are getting harder and harder to find new ones, as most make the switch to complete computer control of I/O
