Sony has unveiled the PlayStation 4, and the big debut is trending on social media this morning.

The PS4 is the first update to PlayStation since the PS3 came out in 2006, and it's packed with more power, better graphics, faster processing and what Andrew House, president of Sony computer entertainment, calls, "a new social dimension."

The new box itself was not revealed during Wednesday's event in New York, but we did learn that in addition to gaming, the PS4 will have a "deep feature set," including access to streaming media from Netflix, Hulu and Amazon (just like the PS3) as long as you subscribe to those services, and the ability to stream your game on the web so people anywhere can watch you play and even offer you advice. We DID get a look at the new controller which looks similar to the PS3 handheld but will now include a touchpad and a 'share' button.

That's probably the biggest change in the PS4 -- the sharing. A new "friends network" will be less anonymous, and Facebook will be integrated into the machine as well. The word "social," came up a lot in the presentation. 

Sony didn't say exactly how much the PS4 would cost or when the PS4 would hit stores, only that it will be out "Holiday 2013."

Microsoft is expected to announce its next Xbox system at the E3 conference this summer. Nintendo's updated game box, the Wii U, went on sale last November.
