FWIW, the A9G is a 2019 model. The similar A9S and the A8H were the 2020 models (but no new 77" last year). My impression is that the A8H was basically an improved A9G, but I didn't own either of them. Personally, if I wasn't comfortable with the current price of the 77A80J, then I'd wait until November to buy it. I wouldn't buy the A9G now.
