The PlayStation 3 (PS3) will be Sony's seventh generation era video game console in the PlayStation series. It is the successor to the PlayStation 2 and will mainly compete against Nintendo's Wii and Microsoft's Xbox 360. Sony has announced that the PS3 will be backward compatible with PS1 and PS2 games. At the moment, little is known in public about the PS3 apart from its hardware specifications and the reports that it will be based on open APIs for the game development.
The PS3 was officially unveiled on May 16, 2005 by Sony during an E3 conference, where the console was first shown to the public. A functional version of the console was not at E3 or the Tokyo Game Show in September 2005, although at both events, demonstrations were held on devkits (for example Metal Gear Solid 4: Guns of the Patriots) and comparable PC hardware, and video footage based on the predicted PS3 specifications was produced (for example for Mobile Suit Gundam).
Games in development
Main article: List of PlayStation 3 games
As of March 2006, there are already over 230 PS3 games announced by multiple developers and publishers, like SCEI, Electronic Arts, Konami, Namco, Capcom, Square Enix, Sega and many others. As well as announced titles there are likely to be many 'secret projects' already under development.
Most developers have already announced games for the PS3. Some anticipated ones include Metal Gear Solid 4: Guns of the Patriots, Killzone PS3, Resident Evil 5, Devil May Cry 4, "Silent Hill 5", Shin Megami Tensei, Armored Core 4 , Unreal Tournament 2007, Resistance: Fall of Man, Grand Theft Auto 4 (provisional title), Final Fantasy XIII (tentative), Sonic the Hedgehog, and Tekken 6.
At the E3 2005 Press booths, Sony showed some pre-rendered and some real-time videos of games in development with the codenames Eyedentify, Vision Gran Turismo and MotorStorm. Also shown at E3 was a Final Fantasy VII technical demo of the opening sequence remade for the PlayStation 3 system. Square Enix stated afterwards that there aren't any plans for a remake of Final Fantasy VII at the moment, but that there is, indeed, a Final Fantasy title in development for the PlayStation 3. At this time, 3 games have been mentioned as PS3 launch titles: Lair from Factor 5, Warhawk from Incognito Entertainment, and Unreal Tournament 2007 from Epic Games.
The PlayStation 3 will be compatible with all PlayStation 2 and PlayStation games. In a recent interview Ken Kutaragi stated that backward compatibility will be achieved through a combination of hardware and software.
At the PlayStation 3 briefing on March 14, 2006 in Japan, Sony revealed that the PlayStation 3 will display legacy recoded PlayStation titles in high-definition resolutions. However, backwards capability will be limited to only games that have strictly adhered to Sony's TRC (Technical Requirements Checklist). On April 24, 2006 the website GamesIndustry.biz reported that Sony Computer Entertainment Europe in the UK were working on the Playstation 3 emulation which is being performed purely in software, similar to the backwards-compatibility mechanism on Microsoft's XBox 360.
The PS3 will not be backward-compatible with some of the hardware peripherals of the PS2. For example, memory cards for the PlayStation and PlayStation 2 will not work on the PlayStation 3 hardware. Instead it was announced that the PS3 will use the Sony Memory Stick, and SD/MMC memory cards to save games. The Memory Sticks will be able to store saved games for both PS1 and PS2 games. However, with the announcement of a standard 60 GB HDD with the PS3, a hard drive game saving system is very likely.
Peripherals such as MaxAction for PS2, are able to transfer PS1 and PS2 saves to a PSP Memory Stick, making the saves compatible to be read from the PS3.
Online services (PNP)

As an answer to Microsoft's Xbox Live, Sony confirmed a unified online service at the 2006 PlayStation Business Briefing meeting in Tokyo.. The name of the service has been given the working title "PlayStation Network Platform". Sony has confirmed that the basic online service will be free and will have sufficient functionality for online gaming. The online service is being developed jointly by Sony Computer Entertainment and Sony Online Entertainment.
PS3 will come with an online service which is 80 times better than xbox live aparently according to Ken Kuturagi the ceo of Sony Communication/Community:

Overall floating-point capability
In a slide show at their E3 conference, Sony presented the "CPU floating point capability" of the PlayStation 3's Cell CPU, and compared it to other CPUs. In their official press release, the same statistic regarding the PS3 as a whole was reported to be 2 TFLOPS.
The figures are rounded estimates based on addition of the theoretical maximum floating point performances of the processing units in the Cell CPU and those of the RSX GPU. Inevitably, real-world performance for both systems will be lower. Additionally, programmers may find it difficult, initially, to optimize their game engines to make the best use of the highly parallel architectures of both systems, further reducing real-world performance.

Sony to Launch PS3 in Nov 2006
Much to the disappointment of gaming fans the world over, Sony Computer Entertainment (SCEI) has announced that it will launch its PlayStation 3 (PS3) simultaneously in Japan, North America, Europe and India in early November 2006.
SCEI expects to produce nearly one million units of PS3 every month, and plans to launch PS3 globally along with several attractive PS3 game titles.
Sony says that its PS3 offers an unique combination of overwhelming computing power and BD (Blu-ray Disc), allowing users to playback BD software at a high bit rate.
The much-awaited BD format boasts of a storage capacity of up to 50 GB (dual layer) plus robust security, and promises to deliver games and movies with unparalleled image quality.
Compatible with a wide variety of television sets ranging from standard-definition TV to full high-definition TV, the PS3 can also be connected to high-speed broadband network through Gigabit Ethernet.
Milestone Interactive is the official distributor of PS3 within the country.
