I think first would be wait to see how well it can be decoded/transcoded on CPUs for peoples current equipment. Won't be able to have as many concurrent streams as codecs with hardware support. AV2 hardware is probably years away. I'm certain AV2 hardware will succeed unlike VVC which had a blip of support with Intel then abandoned the next generation of Intel chips. I'll switch to AV2 once it has similar adoption to like AV1 today so like 8 years from now I guess. I'm guessing similar amount of time for hardware support to be as ubiquitous. Not sure if it should be quicker with how dead in the water VVC has been for 6 years or slower because people upgrade hardware less frequently now and honestly h.264 is still good enough and AV1 is really good enough so any rush to AV2 will mostly be hyperscalers trying to cut down on bandwidth and storage costs
