Sony finally updated the PS3 to version 2.40, bringing with it the much sought after in-game XMB support.
This is a huge step for bringing the PS3 on par with the Xbox 360 in terms of features (additionally with the inclusion of trophies), but there are still a few features that leave the PS3 really far behind.
There is still no cross game invites. If I’m playing Warhawk (not that I actually do) and someone else is playing GTA4, I can’t send them an invite to join me and they instantly join my group. This is a killer feature that the Xbox 360 offers to ease online gaming. According to Joystiq, the game invite feature will be left up to the developers, very poor choice indeed.
No private voice chat between games is also sadly missing. This is really great on the Xbox 360 since you can talk to a friend and decide which game to play, or keep the connection going while in a game so no one else can hear you.
There is also no universal way to block or mute players. I can’t tell you how many times I’ve had to mute the TV or remove my headset due to a 12 year old screaming since there was no way to mute the voice chats.
