I agree again, but am also curious if it would need a whole upgrade, with a new chip or something. Also your devices would need to all support hdmi 2.1 (Blu-ray player, chord, and you’re hdtv all have to work with 2.1. We’re seeing 8K TVs, and to get fully-featured 8K content to the TV (also, we barely have 4K UHD HDR media, an expensive barrier to entry with Sony opting not to have a 4K UHD Blu-ray player in the ps4 pro despite then owning the format & a large selling point for the PS3 was the built in Blu-ray player, but off topic.)
Since even 4K is higher resolution than most people need, given common TV sizes and seating distances, 8K is really overkill atm. From a consumer/marketer stand point, without unlimited money lol, it may seem like a move for future proofing. One that, unless perhaps an customization option for those inclined with the disposable income, that’s too soon IMHO. Especially given the assumption increased price tags.
I’d love to be wrong ahah I’m always excited by new technology e.g. WiFi 6 is another atm
