Sony has revealed that cross-game voice chat, a feature which many PS3 owners have been pleading for, can't be implimented due to RAM constraints in the hardware.
According to Sony Worldwide Studios president Shuhei Yoshida, games are given priority when distributing the RAM, leaving little to none for feature such as voice chat.
Apparently this is something that can't be changed, so it's unlikely we'll see the feature be introduced in future system updates.
"Once a game gets RAM we never give it back," Yoshida has 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," he added.
Earlier this week Sony cleared up rumors by stating the PlayStation Vita's RAM hasn't been cut by half. It went on to confirm that the upcoming handheld will contain 512MB of RAM, with 128MB of dedicated VRAM. More than enough for cross-game chat we reckon.
