Nobody was talking about PS4 vs Xbox One.But so did PS4 games too. In the end the resolution difference between the Xbox One and PS4 never changed, it just swapped from being mostly 720p vs 900p at launch, to 900p vs 1080p later in the gen, to now being back to 720p vs 900p all over again.
It was about that games on the consoles usually improve during the gen. As devs get more used to it, and design arround it.
Show someone how Last of Us 2, Gears 5,; RDR2 looked and run on their base console in 2013 and it would have blown their mind.
