Unless they have hardware encoder and decoder design done in parallel, otherwise it would be 2028 before a hardware block design is done and 2030 for the earliest product to ship with it. In reality I think 2031 or 2032 is more likely.

And I have been saying the same for quite some time that 20-30% for a generational codec improvement isn't worth it. I think they originally aimed at 50%, and then 40% and then 30%.
