Its actually surprisingly easy to achieve IPv6-only on the eyeballs side 
of the network. The mobile operators are the ones that have been pushing 
this since many of their networks and devices support single-stack IPv6 
much better than they support dual stack.

Most of our HTTP traffic comes from a very small number of sites and 
within the next 3 days the majority of them will be reachable on IPv6. 
Enabling IPv6 on local services like DNS, mail and customer support 
portals will allow more of your network traffic to migrate to IPv6.

For all of the other corners of the Internet you can implement 
DNS64/NAT64 to allow your IPv6-only customers to still get to IPv4 
content. This works very well across a wide range of protocols and 
applications. I have been running behind a NAT64 gateway for a while.

Only a small number of applications fail in IPv6-only & NAT64 
environment - Skype being the only popular one.

I expect that we will be running dual-stack in the core network for many 
years to come. IPv6-only on the access network is a reality today.
