From my perspective in datacenter infrastructure, ipv6 interest has actually declined in recent years.
I think the emergence of a functioning IPv4 market has actually tipped the scales backwards towards v4 unfortunately. I frequently hear from operators that v4 technology (and expertise managing it) for sharing addresses (NAT) is so mature and stable that there isn't much gain for them in the riskier bet on v6.
You would also be shocked at how many also consider the unsolicited ingress connection blocking caused by NAT to be a bonus security feature that v6 doesn't have.
I'm starting to become convinced I will be dead long before v6 dominates the world. :(
