I would have liked to have seen more talk about PSN showing chat, matchmaking etc. Do they have group chat, or groups (parties)? The game-centric style of these events bothers me, especially when they're mostly showing multiplatform stuff. They're basically showing me a long advertisement for a product I'd be able to play on any gaming platform, which is information I can get from gametrailers.
... Still, I've got to search for the UI vid now, because I want to see it. It should have been in the conference. A good example is friends and game invites. How do I invite friends to play games with me? Is it easier than before? What does matchmaking look like? These are all things I want to know that go a long way to making the product seem like a good investment. MS and Sony both totally dropped the ball on that. Compare to the conference Apple did for iOS 7, and these game conferences look silly
