This news is a bit old, but since I saw some people talking about that in the last days on Youtube, might as well post it here.
It's still too early to talk about the next-gen Playstation, but according to some leaks (I'll post the source below), Sony is already working on the Playstation 6. That's probably a given, but some of it's features could have been leaked.
The PS6 should be enhanced by Generative AI, a new technology that allows NPCs in games to feel more realistic, and allows them to have different reactions to the player's actions. There's a couple of good Youtube videos showing the progress on this tech.
The graphics will feature Ray Reconstruction and Path Tracing. This may be true, since some PC games like Alan Wake II already have those.
Another detail shares that it will release after the next Xbox. Sony will take their time, since they're not in a rush to release it.
Of course, take that with a grain of salt, since we have no official word from the company, and who knows if this leak is real.
