I think the biggest one is Facebook friend integration, so I can see how many of my Facebook friends play on the same console as me. Not sure why that hasn't been added. Edit: Lol All the hate for Facebook integration on consoles is unjustified. Being able to find your friends that have online accounts that way saves time... That's what technology is for. I almost feel like most of you don't even want to move forward technologically. As if adding the ability to find your friends is just going to make your life rely that much more on technology... Let me just fill you in on something, if you're enjoying your console, and depending on it for entertainment... You already rely on it for something. So unless you're going to give up gaming in general don't act like adding features to tech is awful.
