Sony might well be announcing and launch A9H around september with hdmi 2.1, but that doesnt apply to panasonic. The specs of the HZ2000 are out on one of the panasonic sites, it supports eARC and ALLM among the 2.1 features, and of course both these features are possible on a hdmi 2.0b chipset. I suspect the rest of the panasonic lineup for 2020 will also support eARC and ALLM. I think if you're looking at a gaming oriented tv with panasonic, you are in the wrong place. If you see panasonic's history, they have never catered their tv's towards gamers. So gaming features or large screen sizes (no 77" HZ2000) is not what they favor, they sell some of these oleds in the professional market to use as a reference monitor in color grading studios.
