I don't want to write 4 posts just to justify my impression. When the consoles fully shipped, I will see if my expectation was right or not.
I agree that SONY has squeezed, but I think they have squeezed out every bit of performance thay can get from a given target prize.
On the other hand it looks like Microsoft has squeezed every bit of performance they can get with current technology and compact form factor.
What is surprising is that the result looks this similar.
Think of it like this, assume that SONY and Microsoft would release another console within three years - what would that be?
Microsoft: there are ALREADY talks about Lockheart - a cheaper console.
SONY: could make a Pro with double the number of CUs, bigger NAND chips (or even more channels?), wider RAM bus with more GDDR6 RAM, ... - a lot more expensive but...
Pricing estimate: XBox One X <? Lockheart < PS5 < System X (< PS5 Pro)
Lets begin with Lockheart and One X.
One X: currently $323
Lockheart: $250..$399
System X: $450..$599
PS5 is almost as performant as System X in every area, superior in some, $50 lower would be enough
PS5: $399..$549
