I've been saying since day one that the leap from PS3 to PS4 is massive. Killzone: Shadow Fall showcased that at launch, and then we had the same kind of next gen graphics on inFamous: Second Son, which was open world. Those two alone quickly showcased that PS4 was much more capable than PS3.
Anyway, it's the same old shit every gen.
-> Console gets announced
-> People say specs are disappointing
-> People base the capabilities of said new console based on cross gen ports saying stuff like "huh, it looks just like last gen, just a bit better"
-> When truly next gen titles hit, these same people still can't recognize that they look vastly superior to last gen titles and say stuff like "it looks a bit better, but it would be possible on last gen with a few concessions"
-> After that, we have the phase in the gen where people get used to pretty new games and forget how ugly and outdated last gen titles look now, so they glorify them with nostalgia goggles
-> And finally after 3 or 4 years into the generation people admit that it indeed looks stunning
Looking forward for this cycle to repeat with PS5. .-.
