IPv6 is already over 1/3 of traffic in the US, due to cross 50% this year. There are holdouts like GCP where you have to pay for more v4 usage but v6 isn't available but really deployment is doing quite well compared to 5 years ago. Also do not expect Asia to try to hold onto v4. I.e. it's slow but it's not being sniffled for the vast majority of users.
At this point the main thing holding back IPv6 adoption is enterprises that don't want to deal with it and home users with routers that don't have v6 function by default.
