Twitch was locked in for Xbox One, and now the streaming service has also been confirmed for PlayStation 4. What's that mean, exactly? After hitting the DualShock 4's Share button, you'll be able to broadcast game footage out to your Twitch channel.
And if you're more into watching others stream, that's part of the support as well. Both viewing broadcasts and creating your own will be free for all users. Sony also revealed that some 20 video services are planned for the system, and Music Unlimited will see improvements. The "faster, simpler, better" service will allow you to have music going in the background while playing games.
