PS3, PS2, and PS1 Games Are Finally Confirmed to Not be Compatible on PS5 - DualShockers

Considering that Sony hadn’t said a word about backward compatibility on PS5 for any previous generation other than the PS4, it stood to reason that everything between the PS1 and PS3 wouldn’t be able to be played on the next-gen platform.

Ryan said that PS4 forward compatibility was a key point for Sony when creating the PS5, but due to its focus on other new technologies like the console’s SSD and the DualSense controller, the company couldn’t make older games playable on the platform.
