I'm also baffled when people say online play is better on Live than with PS3 games, but there are some serious things PSN is still missing. No parties for voice-chat in game means that whole games like KZ2 can't be played in the way I'd like without the game developers doing all the work themselves. Same thing with White Knight Chronicles, assuming it ever comes out: PSN voice chat would be a huge addition to a game which apparently expects people to type messages out while they play a console game.
The fact that Sony had a firmware update and added in text chat without voice chat seems somehow grotesque.
And in summary, I can't believe I just bumped this thread.
