However, consider the fact that there will be v6 only hosts popping up after IANA/RIR/ISP exhaustion. There will be new entrants in the public internet space that cannot obtain v4 addresses and will be reachable via v6 only ... Yep, you can't do NAT64 if you don't have "4". But that said, just because ARIN is exhausted doesn't mean PA space is exhausted so there will be addresses available though it will be tight.
That is exactly what the last 5 /8's are for as I understand it. The last 5 /8's will be allocated to each RIR immediately and I think by now every RIR has a policy for that last /8 which pretty much says: only for transitional purposes
