He was speaking from a developers point of view mainly I think, not as an end user. He's right that Live has a very strict and good infrastructure but the downside is that games are more limited in their implementation unless they have close ties to Microsoft so they can bend the rules. Id not worry either way, seems just is personal opinion not some dramatic assessment by PD of PSN and Live. Perhaps if they had to produce game using Live they might be less complementary too.
