Why do we still need IPv4 when we are migrating to IPv6...

I am working with my management team to implement IPv6, but I got an
interesting question from one of the managers; Why do we need more IPv4 if
we are moving towards IPv6?
A quick background; We are having discussions around IPv4 and IPv6 and the
need to eventually buy more IPv4 addresses to keep a premium level on our
My argument is that we need addresses as long as there are important
services that only do IPv4 (yes, there are still a few, especially in
Norway), and as long as the other ISP are reluctant to implement IPv6
(luckily in Norway, all the major ISPs have already come a long way). When
IPv6 reaches critical mass is the $5000 dollar question which I wish I had
the answer for.
So, any thoughts on this topic, and any qualified guesses on when we no
longer need to do IPv4 and still be able to call our internet product
