I really don't know. Live updates itself as well so the PSN may never catch up. At least, not this generation. Right now it's only real edge PSN has is that it's free. Believe me, that's a huge perk, but when I compare my experiences on both Live and the PSN, I really feel that this is a case where you get what you pay for.
