I am with you mostly on this one, I would have wanted a 4K Blu-Ray drive with it as it made so much sense (it will likely be in PS5 though as most Blu-Ray drives manufactured will be 4K by then
), but the market they catered for (and that is buying the PS4 and PS4 Pro) did. It want a $499 console then or a year after that and the price and specs were intertwined.
Also, get mad at all the people voting with their wallet on Netflix 4K streams and claiming that it has just the same or even comparable quality as a UHD 4K Blu-Ray movie... it was not a business priority, customers would have not rewarded them for it, and it did display 4K movies (digital on demand ones) and 4K (and dynamic 4K
) games. Sony was very clear about dynamic resolution and checker-boarding in the presentation of the PS4 Pro itself and in all interviews. From the moment they announced it, they were clear about what it was designed for and what it could do.
It was not blabbing, it was just talking about an AMD developed feature for the Vega line of GPU’s (talking about features beyond the new Polaris architecture they based PS4 Pro mostly on) that helps reduce bandwidth and increase computation speed in some cases and they said that in those cases it acts as a double rate unit (and thus the numbers quoted). It was not meant as to say they were actually faster than Xbox One X / Scorpio.
The article you are probably remembering:

This is one of the cases where the delivered architectural improvements to let the console punch above its weight a bit and it allowed their first party developers to get some advanced titles to a considerably higher level: check the DF review of Horizon’s PS4 Pro patch for example.
In some cases it is not working as well as they hoped because they bet developers would take more advantage of cross generational consoles without simply relying on brute raw performance improvements alone, but that is what a new generation allows... more and more frequent mod step consoles released will make this problem worse and worse.
Both machines are well designed given their constraints, but are timed and positioned differently. Waiting one more year would have not gotten them s lot more sales than they are getting now (gamers are happy), it would have meant delaying PS5 one more year, and it would have been an extra investment with little to no extra return.
