By plotting IPv6 adoption by progress we see the RIPE region is leading the world with the most "In Production" networks, followed by ARIN and then APNIC. But APNIC is a bit of a surprise. Given the RIR depleted their IPv4 address pool over two years ago, I expected more networks to be in the "Deploying" and "In Production" stages. This implies Asia is using more workarounds, such as NAT and CGN, to delay the inevitable.
So the v6 wave is moving, it's just not progressing as a single aggregate wave and it's certainly not moving as quickly as we expected. And although Serge was right about getting rid of the v6 wave diagram it turns out it was too simple rather than complicated.
