I think we can all agree, that the major thing that is holding the PS back is the interface, as the Xbox has a far superior one, and the PC for that matter too, with services like Steam, Xfire, Teamspeak, which all allowing you to party up before you get in any game. So, that is where I think Sony should focus on improving.
Something similar to the PS store, with TABS and icons, add in a couple of features Xbox doesn't have, Like PS only "Screenshots" that you upload to facebook (No hosting cost for Sony)
