I have been gaming for over 30 years. Been involved when I was a child (Sega vs. SNES, argued SNES was more powerful, yet I loved and owned more of the Genesis software), and witnessed every console war. I never seen the goal posts move from what is considered an exclusive IP with the "1st and 2nd" BS, like I have this gen. It was mentioned last gen, but not to try and discredit a game being exclusive, it was just to show a developer was not owned by the console publisher.
Another thing is, that for the past two generations, when the XB platform often had the best versions of 3rd party titles, even smaller differences than resolution were important factors, unlike now when the shoe is on the other foot. If the power balance changes back to their favor next gen, I imagine we'll see a shift towards the older narrative.
