RIPE already ran on the "1024 addresses for every new member and that's it" soft-landing policy for the past couple of years.
But ARIN does not have a nice policy like RIPE does, so it will be a bit more entertaining this time.
For the record, I make the same complaint every time. Always the same response. "Those were warning signs, but now the end is nigh!"
4.3 billion IPs x $12 per year = $51 billion. If the average cost to actually hold an IPv4 address was even $0.10/month, we would not be talking about IPv4 exhaustion.
My point is, as long as you're willing to spend $12/year just for the IP address, there will be a long line of people happy to sell one to you. But $1 per month for a routable address is at least two orders of magnitude more expensive than network architects are aiming for.
1) more stateless mechanisms will be used (lw4o6, MAP) - which do not give the entire IPv4 address to residential users => so even if the service has an IPv4 address, the clients might have to go through the hurdles to get to it.
Service providers are planning to go IPv6-only, and content providers already note that IPv6 gives a double-digit performance increase compared to IPv4 [1]
2) The residential ISPs will debundle the IPv4 from the cost - given that a lot of the sites average consumer needs (google, facebook, youtube, netflix) are already IPv6-enabled. For this case, you will not be even able to see that something is "wrong". Just the users will click on the link, see it's not reachable, say "huh?" and move on.

There's no panic. The trick with IPv6 deployment is predicting two years in advance the moment will you need IPv6 "tomorrow" - because for a lot of orgs that's how long it takes.
I'll repost a link from the recent NANOG meeting here about the folks seriously discussing their plans of going IPv6-only:

I thoroughly enjoyed the moment when one networking pro (who dealt with IPv6 20 years ago and not since) was telling me he won't have IPv6 till he retires, realized he had his on his LTE connection and was using it for quite some time already! :-)
I repeat myself from another post:
One out of five users hitting google.com and facebook.com in the US today does so over IPv6.
It's going to be a long time before you can't get an IPv4 address at all. But what is going to happen over time is the cost of an IPv4 address is going to go up, since demand will increase, but supply won't.
