Playstation 4 Hardware Specification, Release Date And Price :

PlayStation 4 (PS4) is an upcoming video game console from Sony Computer Entertainment. Announced as the successor to PlayStation 3 during a press conference on February 20, 2013, it will launch on November 15, 2013, in North America, and November 29, 2013, in Europe and Australia, and will compete with Nintendo's Wii U and Microsoft's Xbox One, as part of the eighth generation of video game consoles.
Moving away from the complicated Cell architecture of the PlayStation 3, PlayStation 4 will feature a simpler AMD processor, in hopes of attracting a broader range of developers and support for the system. Sony also plans to place more focus on social gameplay, incorporating a "share" button on the new controller and making it possible to view in-game play streamed live from friends. The console will focus on interactivity with other services and devices, including Gaikai, a cloud-based gaming service that will offer streaming video game content; PlayStation App, which will connect smartphones and tablets into a second screen to enhance gameplay; and PlayStation Vita, which will be able to play a majority of the games through Remote Play.

PS4 price:

Sony announced the PS4 price at E3 - it'll cost $399 in the US, £349 in the UK and €399 in Europe when it goes on sale in November. That's a whole $100 cheaper than the Xbox One.

Sony has confirmed that PlayStation 4 will not natively support PlayStation 3 games. While the company has yet to also rule-out on-console emulation of some previous generations, the company has detailed plans to explore cloud-based emulation of previous generations as a long-term solution to the challenges of backwards compatibility.
Sony is planning to launch a cloud-based streaming service through Gaikai, a company acquired by Sony in July 2012. The service will emulate and render previous generations of PlayStation games, streaming them to the PS4 and the Vita, over the internet.

 What's more, we've gained new insight into the DualShock 4. As we know, the controller sports an integrated touch pad, headset jack, share button, and LED player identifier, but we've now learned that the touch pad features a mechanical button and supports "capacitive type." In addition to the obvious size and ergonomic changes, the DualShock 4 is expectedly gaining a bit of weight, going from 6.77 ounces on the DualShock 3 to 7.4 ounces on the DualShock 4. Details were remarkably scant at the event regarding the PlayStation 4 Eye, which has been revealed as having a 1280x800 pixel sensor capable of capturing video at 60 frames-per-second — a significant leap over the Kinect's 640x480 30fps sensor. It also won't have to eat up a USB port on the console because it has its own dedicated port. It will be able to be used for "walkthrougs, taunting in killcams, login, and speech recognition." It can also read whether you and a friend switched places during a split-screen game.
