The pro came out 4 years later, yes, not at the same time like Xbox did when they built the system in mind.
They didn't just made one and brought the other afterwards.
The pro came out 3 years later than the PS4 and shared very similar architecture but it came out four years ago, the post I was responding to was talking about 1440p and why they could do that for the Pro and be ok but not the Series S. My point is that was a 4TF machine that was meant to improve games made for a 1.8TF machine and almost all we got was a resolution boost and slight framerate improvements. The new gen shouldn't be targeting 1.8TF machines as a baseline for what they can handle graphically, they'll be asking more of the GPU to begin with and that's before any kind of res boost. The GPU in the Series S is more advanced than what's in the Pro so it's not a straight up comparison but it's also going to be asked to handle more advanced graphical techniques and more demanding games.
