If you are in need of new address space, your choice is to go hunt for IPv4 space, which will get harder and harder, or upgrade to IPv6, which will become easier and easier.
IPv6 Internet is working even now, but completely useless. Because of there is no resources at all.
I don't need an IPv4 address to talk to my mail server in order to send this message. (Although the mail server still needs an IPv4 address; RIPE's mailservers are IPv4-only ...) So even though you can't do a search and replace and get rid of IPv4 everywhere today, I'm pretty sure EVERYONE can add more IPv6 than they have now.
In my opinion, the concrete goal is make 51% of _resources_ (not users) to be reachable through IPv6 before we run out of IPv4. If it succeeds, other 49% will go with "the majority", if not - IPv6 migration completely fails and something other (NAT, secondary market of IPv4, higher level proxies over non-IP protocols, ...) will be implemented instead.
I don't think it's a good use of our time to consider the possible failure of IPv6. Adoption will be slow, but the future goes on for a long time, it doesn't have to be fast, we can still get where we need to be eventually as long as we keep going in the right direction. Iljitsch
