It is not readily apparent to me why the availability of a chip ten years
from now will affect the 480 units that are installed today.

Today, would you rather own a 20 year old King radio or a Narco? I have
an old King KX-155. There are thousand out there, lots of parts and
lots of avionics people working on them. Hell, even the KX-170b still
has a HUGE install base with support for most problems.
