I have said before twitch would be coming to PS4 and it is! During Sony’s Gamescom conference they announced twitch support for the Playstation 4, it will allow you upload and stream your own videos to the platform. You can also view and watch other twitch videos on the Playstation 4 like what you can do with UStream.
Plus an improved Music Unlimited app will be available at launch, the improved application will allow you to listen to your music unlimited library while playing a game or doing anything else on your Playstation 4. Not only that but with a touch on the PS Button it will launch quick controls for your music so you stop, skip, pause and more while playing killzone.
