Sony has confirmed that they are developing a new console called the Playstation 4. Although Sony didn’t show off  the Playstation 4 system itself  but it nevertheless  had lots of information to share about the new console, and so we have gathered all the confirmed details on Sony’s Playstation 4 into one place.

Tech Specs

• The PlayStation 4’s main processor is a single-chip custom processor, a x86-64 AMD “Jaguar” with eight cores. A second chip is dedicated to managing uploads and downloads.
  
• The GPU is also an impressive AMD next-gen Radeon-based graphics engine that can make 1.84 trillion calculations a second.

• The PS4 packs a borderline improbable 8GB of GDDR5 memory.

• As well as a built-in hard drive (the size is yet to be confirmed), the PS4 also features a 6x speed Blu-Ray drive (compared to the PS3’s 2x speed one), an 8x speed DVD drive and USB 3.0 for high-speed transfer.

Console Features

• A new suspend mode lets you “switch off” the PS4 and store the game’s current state in its memory. When you return to the system later and press the power button, the game will instantly carry on where it left off, with no need to boot the system and load the game.
  
• The new PlayStation 4 menu screen will let you see what your friends are doing, while also recommending games, TV shows, movies and music to you. These recommendations will be specific ones unique to you, based on your previous downloads. For example, if you’ve spent a lot of time playing FIFA 13, it’ll recommend the FIFA 14 demo when it’s available.

• The PS4 can run multiple apps at once. For example, while playing a game, you can load a web browser to check out walkthroughs.

• The PlayStation App is a new app that Sony will be releasing on iOS and Android devices, allowing you to use your smartphone or tablet as a second screen that acts as a map or lets you see how a friend is doing in that particular section of the game. It’s a similar idea to Microsoft’s SmartGlass and, of course, the Wii U GamePad.

• It has been confirmed that the PS4 will NOT block pre-owned games.

Network Features

• Digital titles purchased from the PlayStation Store can be played as they download. The system will download the first part of the game so you can start playing it quickly, then continue to download the rest of the game’s assets in the background as you play. This also implies there will no longer be a need to install games as with the PS3.

• While Sony isn’t completely blocking anonymous usernames, it does want to let people play online with their real names, integrating their gaming with social networks such as Facebook.

• Gaikai technology will let you instantly try out sections of any game on the PlayStation Store. While in which way this happens isn’t yet clear, but it’s likely it will come in the form of timed streaming demos.

• The PlayStation 4 can be updated while the console is switched off, potentially putting an end to the dreaded lengthy firmware updates that annoyed PS3 owners.

• If you’re stuck in a game you can ask your friends to help you. This can either come in the form of text comments that will appear on the screen like notifications, or they can actually take over the game’s controls and beat a section of the game for you.

• The system does NOT require an always-online connection.

DualShock 4 Controller

• The controller features a touch pad on the front. Many outlets speculated that the interactive pad was a touchscreen, capable of displaying graphics. It now appears to be more like the touchpad on the back of the PlayStation Vita.

• A new “SHARE” button lets you add screenshots and gameplay footage to your Facebook feed.

• An LED Light Bar, similar to the LED ball on the PlayStation Move, sits along the top of the DualShock 4. Much like the Move, it can change colour for various needs (player indicators, damage indicators etc). It can also be used for Move-like controls. 

• The Start and Select buttons have been scrapped in favour of a single Options button.

• The controller’s built-in speaker will let you hear additional sounds.  Alternatively, there’s also a headphone jack which lets you hear these sounds in greater detail as well as friends’ voices during chat.

• The PS4 will come with a mono headset provided.

• There’s a new built-in sensor inside the pad which Sony promises will enable “highly sensitive motion control”. 

• The controller’s existing buttons – most notably the dual analogue sticks and L2 and R2 buttons – have been redesigned in accordance with developers’ wishes and the vocal gaming community.
  

PlayStation 4 Eye

• The new PlayStation 4 Eye new camera, expected to be bundled with the system, appears to be Sony’s answer to Kinect. It features two high-sensitivity 1280×800 cameras with wide-angle lenses and 85-degree diagonal angle views which, according to Sony, “can recognise the depth of space precisely”.

• Sony claims the camera can “cut out the image of the player from the background” or track their distance from the TV, allowing players to move their bodies to play. Players can also sign in with facial recognition.

• The PlayStation 4 Eye also includes four microphones, allowing it to accurately detect sound and where it originated from.

• Much like the previous Eye with the PlayStation Move, the new Eye tracks the LED Light Bar on the front of the DualShock 4 controller,  allowing for Move-style controls. With every PS4 owner potentially having Move-like controls instead of it being optional, this could have very interesting outcomes for upcoming games.
  

The Games

• Killzone: Shadow Fall is the fourth main game in the Killzone series. 

• inFAMOUS: Second Son is the third inFamous game. It’s set in Seattle seven years after the events of the previous games.

• DriveClub is a new racing game from Motorstorm developer Evolution Studios. Its focus is is on social connectivity, with players able to create “Drive Clubs” and challenge others. Evolution claims this is the game it always wanted to make – the Drive Club name was trademarked almost a decade ago – but the technology is only ready now.

• Watch_Dogs was shown during Ubisoft’s E3 press conference last year but it was finally confirmed for PS4 last night (as well as PS3, Xbox 360, Wii U and PC).

• Blizzard announced its return to console gaming with PS3 and PS4 ports of Diablo III.

• A series of tech demos shown included Capcom’s Deep Down, Quantic Dream’s facial animation tech, Square Enix’s Agni’s Philosophy demo.

• A massive 149 development studios and publishers companies have committed to supporting the PS4.
