As you’ve probably read by now, cumulative PS4 sales have now surpassed six million units worldwide following the successful launch in Japan just over a week ago. It’s truly humbling to see the rate at which gamers across the globe are choosing PS4 as their next gen console of choice. Even more exciting is what happens when gamers power up their PS4s. In the United States, more than 90% of PS4s are online, enabling gamers to connect, compete and share their greatness with friends and fellow gamers.

There have now been more than 3.6 million live broadcasts, and more than 56 million spectate sessions on PS4 through Twitch and Ustream. In fact, since January 1st, PS4 gamers account for 20% of daily broadcasters on Twitch. PS4 owners are also embracing the Share button on the DUALSHOCK 4 Wireless Controller, with more than 100 million shares captured as fans show friends their latest achievements on Facebook and Twitter.

And soon, you’ll be able to share your greatness in new ways. Developers are beginning to take advantage of PS4’s new interactive live broadcasting gaming features, integrating modes that allow broadcasted gameplay to become interactive for spectators. Even as a viewer, you can now influence livestreamed gameplay.

For example, Dead Nation: Apocalypse Edition features a built-in Broadcast+ mode where you can stream your gameplay while viewers on the PS4 or a web browser influence positive and negative effects during gameplay. More social feedback is on the way too, with Dynasty Warriors 8 Xtreme Legends Complete Edition in March and Daylight in April.

We love the enthusiasm that all of you have had for the PS4 since launch, and we can’t wait to share more great games, experiences and features with you soon. Greatness awaits!
