I still think that while the hardware may be ready by now, the software certainly isn't. Not only does an IPv6 break a lot of old software,that's not designed for the stack. Even today, not all network librarys do support IPv6. It's nothing that can't be worked out, but we are just not there yet and will never be there until a forced adaption comes into play.
