How many 10 year old pieces of kit do you have on your network?
Ten years ago we were routing appletalk and IPX. Still doing that
now?
Ten years ago companies were still selling ISDN routers which still
insisted on classful addressing. Got any of them left on the network?
I'd expect that v4 will still exist in legacy form behind firewalls,
but I think its deprecation on the public internet will happen a lot
faster than anyone expects.

Only until v4 becomes more expensive (using whatever metric matters to
you) than v6.
After you pass that tipping point, v4 deployment will stop dead.
