Let's be real for a second, there are plenty of backbone-ish companies 
that have been around long enough to accumulate tons, and tons of IPv4 
space. 

I remember an old SP that used to give every PC in their NOC, possibly 
their whole company, a /24 and /16s weren't hard to get either. Lots of 
shops that had IP-based hosting that have gone name-based probably have 
tons of available space too.

The "no more IP addresses available" will affect folks unevenly... if I 
were to guess, mostly the folks that aren't large/old enough to have gobs 
of space lying around but are too large to get provider space. I'm also 
guessing that these guys are the ones creating the most pressure for IPv6 
in their upstreams, as it serves their interests to make IPv4 unneeded as 
soon as possible.

The next big surge of IT spend that isn't about reduction or 
consolidation will create pressure on Enterprises to use more address 
space, and if they are nearly out of IPv4 space (with firewalls, NAT, 
VPNs, etc, not a lot of pressure there) they will push their SPs for it. 
Government contracts for telecomm all require IPv6 support, and all the 
vendors on them say they support it, but gov't customers trying to order 
say that is a no-go. (As of two weeks ago)... so even gov't isn't a big 
enough buyer to make this happen sooner.

While some companies will have plenty of IPv4 space for a long time, not
all the people they communicate with will.  Some of them will be forced
into using IPv6 sooner rather than later.  All companies need to be ready
for that regardless of how much IPv4 they have.
