Well, to be quite honest, I don't think they'll take it *that* far. I think they're going to take the same direction Apple/iTunes did when they announced Ping (or whatever that thing is called). However, I'm quite curious about their plans to "integrate" the new console to social networks. More than just sharing achievements via facebook/twitter?
In the meantime, I googled about this and not much has come up. So we're better off waiting till the 20th to find out. ;3
