IANA ran out in Feb 2011. APNIC followed in Apr 2011. RIPE in 2012, LACNIC in 2014 and indeed ARIN in 2015. The only RIR that still has some left is AFRINIC, forecasted to explete in 2018.

At least they won't just give ity away. They may sell some if they need the money, but the amount of IPv4 freed that way will be a drop in the ocean.

Yep, present rate about EUR 10 for an address.

It may never totally go away, but I expect that when IPv6 takes hold, it will fade to the point that for all intents and purposes it will be gone. IPX is still around in some corners, but as far as I a m concerned it is gone.
Maintaining dual stack is an extra effort that I expect manufacturers will try to get rid of when possible. One day a bug will crawl in in the IPv4 part or a router that nobody notices because everything is done via IPv6. And then when the bug is finally noticed, someone might offer the suggestion that instead of fixing the bug, to just drop IPv4 alltogether.
I would not be surprised if this were to happen in the coming decade.

And that will be the case for most of your competitors as well.

Indeed. It is now or never. Any one waiting any longer runs the chance of being too late.
