H266/VVC has a five year head-start over AV2, so probably that first unless hardware vendors decide to skip it entirely. The final AV2 spec is due this year, so any day now, but it'll take a while to make it's way into hardware.

H266 is getting fully skipped (except possibly by Apple). The licensing is even worse than H265, the gains are smaller, and Google+Netflix have basically guaranteed that they won't use it (in favor of AV1 and AV2 when ready).

VVC is pretty much a dead end at this point. Hardly anyone is using it; it's benefits over AV1 are extremely minimal and no one wants the royalty headache. Basically everyone learned their lesson with HEVC.

If it has a five year start and we've seen almost zero hardware shipping that is a pretty bad sign.

IIRC AV1 decoding hardware started shipping within a year of the bitstream being finalized. (Encoding took quite a bit longer but that is pretty reasonable)

When even H.265 is being dropped by the likes of Dell, adoption of H.266 will be even worse making it basically DOA for anything promising. It's plagued by the same problems H.265 is.
