compact and well-designed box at a reasonable price, and Sony's open approach to game sharing and used games has gone down a whole lot better than Microsoft's rather restricted take. Most importantly, there are some very promising games on their way for the new console, showing off its capabilities but also looking like they might be a lot of fun to play.
Here's the official listing of the PS4 specification, released after the event.
Single-chip custom processor

GPU: 1.84 TFLOPS, AMD next-generation Radeon™ based graphics engine
Hard Disk Drive:
Optical Drive (read only):
I/O and communication:
Super-Speed USB (USB 3.0)
Ethernet (10BASE-T, 100BASE-TX, 1000BASE-T)
IEEE 802.11 b/g/n

PS4 PROCESSOR AND GRAPHICS
It's been widely-known for some time that the PS4 would use AMD technology, both for its CPU and GPU elements – as is the remarkably similar Xbox 720. AMD hardware was confirmed at the launch, although the precise architecture wasn't discussed in much detail.
Hardware details were thin on the ground
Even what proved to be the most reliable leaks said that the PS4 would have 4GB of system memory. It was theorized that use of a single pool of fast GDDR5 memory would more than make up for the (rumored) more fragmented 8GB memory system of the 'Xbox One'. However, when the reveal came, we were pleasantly surprised to find that the PS4 will have a whopping 8GB of super fast memory.
It's possible that this was due to Sony telling developers to develop launch games within a 4GB limit. Final hardware wouldn't have been finalised when development started, and Sony would know exactly how much memory overhead the PS4's cloud gaming, video capture and operating system would have. So giving developers a smaller limit to work within would have been a safe move. Pure speculation, but it does make sense.
This unified memory system is seen by Sony as its main advantage against the Xbox 720, though only time will tell have much difference it will make. Sony’s lead system architect is certainly in a bullish mode though, describing the system as ‘Supercharged’ here: PS4 lead architect describes its "supercharged PC" design
The eight-core Jaguar AMD CPU and the powerful 1.84TFLOPS AMD GPU were both confirmed. There wasn't any details about the architecture of the latter though, an area where hardware leaks, from the largely-reliable http://www.vgleaks.com, have pointed to a significant advantage for the PS4.
The new PS4 interface looks to modeled after the latest update to the current PlayStation Store on PS3
The interface on the PS4 will be about much more than launching games, playing Blu-ray and having game-based social experiences with your friends. Sony is keen to also provide a wide range of content - as its Head of Worldwide Studios stated recently: PS4 will continue battle for living room says Sony's Shuhei Yoshida. Yoshida noted that they hadn’t wanted to distract attention from its games playing potential at the initial unveiling but that there was a lot more to the PS4 than that.
PS4 CONTROLLER - DUALSHOCK 4
The new PS4 DualShock 4 being officially unveiled
It has a small touch pad above the analogue sticks and a colored light on the front. In this respect it includes functionality we've seen on both the Vita (which has a rear touch pad) and in Sony's motion-based Move controllers. A speaker is also built-in, allowing for local audio effects and a headphone socket too - probably for headset use, but we're also hoping for Bluetooth audio for easier headphone use while playing - very handy for split-screen gaming.
The button layout has been rejigged, with a new 'Share' button added for quick access to social media. Check out our Cloud Gaming section for more details.

PS Eye Camera For PS4
There's also a new Eye device with two 1,280x800 resolution cameras – 4x the previous camera's resolution. This gives increased accuracy to pick up the existing Move controllers or the new DualShock 4. You can read more about this at PS Eye revealed for PS4.
