Ouch… well, at least now we know the real reason Sony was so reluctant to include cross game chat in one of their updates. According to an interview Eurogamer had with Shuhei Yoshida, the Sony Worldwide Studios president admitted that the PS3 does not have enough ram to implement cross-game chat. The PS3 has 256MB of RAM each for the system and video, and all of it is used to run games. He states that the games themselves implement the voice chat feature, not the system. Because of the infrastructure of the PS3, and the possibility of alienating owners of newer PS3 models, Yoshida stated “It’s not possible to retrofit something like that after the fact.”

So there you have it. If you’re curious, the Vita has 512MB of RAM and 128MB of video RAM. So that little thing is quite a beast in that department.
