I just think you're exaggerating how bad the problem is:
a') IPv4 isn't really "failing" at all, there are some issues that NAT introduces, as well as additional workload and routing fragmentation. For the most part the solutions are new/more equipment (which conveniently will support IPv6) and sensible deployment strategies (which conveniently will support IPv6 upgrade paths)
b') isn't a valid premise, because it's your conclusion based on premises... So treating it as a forgone conclusion is a bit arrogant. Behind the scenes, the work being done to transition to IPv6 is very non-trivial, but the transition has already begun and nothing serious has broken yet.
c') There is a smooth transition happening right now My servers are available over IPv6 without any trouble at all, and my ISP has already done wide-scale testing to ensure that they're ready to flip the switch when it makes sense.
I'm sorry, but you've just bought into the fear-mongering from sysadmins that want more money or think they need to scare management into keeping them around. There are some people who have a lot of work to do to make the transition happen, but they've been on the case for several years now and generally speaking everything is going quite well.
