Netflix has been providing IPv6 service (albeit not with 100% coverage) for the last few years. In practice, it makes sense for the largest bandwidth users to move first, because that means ISPs can deploy IPv6 in order to reduce the load on their NAT infrastructure. (And most ISPs will be using NAT sooner or later, because giving everyone their own IPv4 address is simply not sustainable.)
