After being included on countless PlayStation 3 fans wishlists and even news that PS Vita will include it, today Sony Worldwide Studios president Shuhei Yoshida admitted cross-game chat is not possible on the PS3 due to memory restrictions.
To quote from Eurogamer.net (linked above): "Cross-game voice chat is not possible on the PlayStation 3 because of memory restrictions, Sony has revealed.
The PS3's RAM is gobbled up by the games it runs, which prevents the much-desired feature from being implemented, Sony Worldwide Studios president Shuhei Yoshida told Eurogamer.
"Once a game gets RAM we never give it back," he said. "It's not possible to retrofit something like that after the fact."
Vita has 512MB of RAM and 128MB of V-RAM, compared to the PS3's 256MB of system RAM and 256MB of video RAM. This enables features such as cross-game voice chat to run in the background while games are being played.
On the PS3, however, things are different. "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."
