Have we already known this about the share button on DS4, live streaming with DS4 share button. From an interview with Scott Kirkland at Evolution games. Sounds different than just uploading the recorded gameplay. Would be awesome if we could live stream the game.
Scott Kirkland: "It’s awesome. I mean, the controller has a Share button on it. You hit the Share button, if you’ve configured your streaming service connection, then the stream is out there. I don’t think there have been any announcements about the kind of partner services who’ll be providing that, but in development we have simple tools, the service runs on my desktop PC, I hit the Share button on my devkit and I can just see what’s going on in my devkit through a web browser window. That’s brilliant. You get the output from the camera as well so you can see your friends’ reactions to your overtaking manoeuvres or spectacular crashes."
