If past Disklavier history is anything to go by, it's unlikely that any specific DKC controller will ever be upgradeable, at least not if it involved hardware changes (adding functionality via software updates or the addition of DSR1/DCD1 units has been available for some models in the past), not least due to development costs. Also, the Mark III has now been superceded by the E3, so further development of the Mark III would be unlikely.
Mind you, with processing power becoming cheaper, I could see some sort of universal Disklavier box, similar to the DCD1, appearing, which would connect to any (or most) past Disklavier models, either directly or via MIDI, but I certainly am not aware of any such animal appearing in the near future.
