We all knew the reason why Sony was unable to implement cross-game chat, after it was such a most requested feature. Sony’s Shuhei Yoshida has revealed that it is indeed due to RAM.
“Once a game gets RAM we never give it back,” he said. “It’s not possible to retrofit something like that after the fact.”
“The game has to use its own memory to do [in-game voice chat]. There’s always voice chat in the game. But it’s a part of a game feature. It’s not a part of an OS feature. That’s the reason in terms of the ability to have voice chat across different games.”
However, the Playstation Vita has a lot more RAM, and has the cross game chat feature. So, if you are expecting a magical firmware update for the PS3, that enables cross-game chat, it won’t happen.
