The PS3 is set to lost cross-system functionality from June 2020, Sony has announced. This means that the PS3 will no longer be able to send messages to other PlayStation systems, nor will the PS3 be able receive any messages except from other PS3 consoles.
These changes will take effect from Tuesday, 30th June 2020 according to PlayStation Japan. The PS3 will also stop reporting what games are being played on other devices, including the PS4 and the PlayStation App.
This does not affect messaging between the PS4 and the PlayStation Vita, which will continue to work as normal. But this does mean that Sony is slowly removing support for the PS3, given that the console is now over 13 years old.
So in like January last year I was in a ps4 group chat with some friends and one of them I didn’t like. A few days later that person left and I said some not so nice things about that person for example, I never liked that guy anyways. Because he left on ps4 if he was to ever go on a ps3 would that chat still remain and display the messages I sent after he left or will it disappear because he left on the ps4 already? This was all before messaging between the ps4 and ps3 was stripped.
The messaging system is generally linked across consoles and the PS App, so if the person left the PS4 group, that would mean the group has also been left across all other devices and consoles. So they won’t have received any further messages on any device once they’ve left.
