I think that's a pretty bizarre way to measure IPv6 deployment. The _last_ applications to support IPv6 will be the widely popular apps that depend on an extensive infrastructure of servers that are currently associated with IPv4. Email and the web both fall into this category. And as long as a site (practically speaking) has to support SMTP over IPv4 in order to accept incoming mail, and HTTP over IPv4 in order to make its web pages readable to most viewers, there's little incentive for that site to advertise an AAAA record for either server.
