From the Verge. Pretty much what I said in the OP.

"Find your favorite seat in front of the TV, then measure the distance between your head and the screen. Now measure your screen diagonally. Do you own a 65-inch or 55-inch TV, the most popular sizes? Do you sit 10 feet away or more? Then no, the PS5 Pro is probably not worth $700. Not even if you have 20/20 vision like me. The improved visual fidelity just isn’t tangible enough at that distance"

Digital trends. Skip sward to final thoughts at 9:30. Pretty much as I said in the OP. 

Get ready for the sane people to be disappointed and the not so sane to defend this thing to high heaven to justify their purchase.

The distance between my head and the screen is about 1 inch :p

Actually PSVR2 projects the 'screen' at about 2 meters, 6.5 ft.
With an fov of 110 degrees that corresponds to watching a 250" TV at 6.5 ft distance, or 400" TV at 10ft.

Anyway if you currently prefer quality mode for visuals but would like to play in performance mode instead, then the Pro is for you.

People are already in a good position to decide for themselves if they have a PS5 at home. Jump between fidelity and Performance, do you see a difference? If so, PS5 Pro will give you the fidelity image quality at performance frame rates. I've got a 55inch TV and sit about 2meters from it. The vast majority of Third party games typically have big dips in image quality when jumping to performance mode, sonys first party titles not so much. It will vary a lot by game 

Also in the review:

"But if you sit closer, Sony’s new game console can make select games look amazing. Blades of grass, pillars of rough hewn stone, the weave of a backpack — they pop at higher fidelity. It’s enough of an improvement that I found myself wanting to sit closer, or stand, or even plug the PS5 Pro into a 4K computer monitor to use it like a gaming PC."

"But after spending several straight days swapping back and forth between my original PS5 from 2020 and the new PS5 Pro, testing over a dozen games in all their different graphical modes, I think there’s something to that “best of both worlds” claim."

Yep. But people aren't going dragging their couches for this. I'm in a fairly small room and my distance is roughly 9 feet. Europe has smaller TV's too to the size of the room, the east even smaller. Japan tiny. But thing is many upper middle class who are going to buy this have massive rooms and yeah, probably bigger TV's but I'll bet that ratio is the same as me, 9 (8 if one the edge of the seat) feet from a 50" which is the most comfortable distance. 15 feet from a 70" like would be the same ratio.

But as someone said above we already know if it'll be worth it, users can simply switch between fidelity and performance now and check the distance, 4 feet is where it starts to become even slightly noticeable and 3 to 2 feet to actually see the detail. 

Again, this thing has GOTTA be used to enhance games in some other manner in future game with the same way the Next gen patches for Cyberpunk and The Witcher 3 had actually noticeable improvements to things as simple as crowd density (isn't that CPU though) or particle effect like in Ghost of Tsuhima. There has to be some other avenue for devs to build on the tech rather than this combining performance and frame rate. For the money, they have to do more. In my opinion.... like Dragons Dogma or FF7 rebirth if all titles were like those then it'd be so worth it. 

Yeah, PSVR 2 will make better use of this. I seen your favourite game on the list, Cycube VR. 

Sorry but if I have to drag my couch over to see the full effect to justify my $700 console, then I deserve to be robbed lol. The Verge reviewer is literally having to go out of their way to find the best use for the Pro. Like, come on, what are we doing here? lol

PSVR2 users are definitely the biggest winners here though in terms of noticeable improvement since they're always inches away from the screen..
