Consoles shouldn't be focused on 4k and 8k. Pc barely touches 4k imo because you are basically running games at 4k 60 fps and you lose the quality of higher refresh rates.
If pc isn't there fully yet, console do not have a chance at reaching those resolutions with stable framerates. They don't even use true native res in all titles because they will upscale resolutions to be the current one you have, causing a blurry effect on the screen. AKA fake resolution.
Also im sorry but tvs are a rip in some aspects of specs. You save money buying a 1ms 1080 144hz monitor instead. There is no point in buying a tv that has higher refresh than like 60 or 4k when most content either doesn't stream above 24fps or its all in 1080. A lot of media is stuck in the past, and until they stop trying to be cheap and record stuff at higher frames and better res it won't matter that much.
The new ones are going to be running on navi from AMD and zen, so they will get a decent buff, but not to the point where they still won't be held behind. Companies have to look at cost. It is getting close tot he point where you might as well buy a pc because you are not only gonna be sending more moeny than before, but you are forced to buy online subscriptions that end up making you waste money.
