Sony is a Japanese Multinational company. It is one of the leading manufacturer of electronic products.

Sony is finally releasing its PS4 after a long time, this will be more powerful but it will not play the PS3 discs which will mostly inserted by the consumers. Sony didn't give any hint about its price till now.

Sony has decided to launch its PS4 this week. However, Sony didn't display any physical dimensions and its console and they also didn't tell clearly about its compatibility with PS3 which was released in November, 2006.

There are 77 million users of PS3, it is not possible that Sony will change its aging console anytime. The thing which is not clear, which software of PS3 will not be supported.

Lack of backward compatibility means that it will not supported with PS3 games, and there will be no issue with PSN (PlayStation Network) titles, which are downloads, said by Michael Pachter, MD of equity research.

PS4 will use the cloud bases services and Sony has told us that the games which are purchased via PSN can be carried in PS4. It is also possible that Sony can provide direct transfer of PSN titles or owners can access their downloaded titles through Gaiki powered cloud server.

The bis question and confusion is that, why Sony will not give the PS3 games and software on PS4? while it is not difficult for Sony to make it possible as they have already done this before when they launched its PS3 then it was compatible with PS2 games and PS2 was also able to play the original PS games.

PS4 has power to do so, Sony just need to create a VM that will accept the games, it is vvery simple, said by Rob Enderle, a principal analyst.

Another senior analyst Billy Pidgeon that Sony can shut down PS3, which has a large number if installs ans users.

The PS4 is the better robust machine, which means that it will have the more titles. It is built on PC chipset, so it will be easier for develop and easier means that it will be lower cost which means more content. It is used x86 platform and the beauty of x86 platform is that it can get a lot of code from open source Linux world and PS4 also use the drivers for some of its hardware.

PS4 is the new version of original DualShock Controller, with an LED touchpad, older version didn't have this and from steering wheels to move controller can be used with PS4.

Usually, you get new things with new accessories like new console and new things usually came when older one has some problem, controllers specially, like the old version didn't have the touchpad while PS4 has touchpad.

It seems very difficult to guess the price of PS4 but some senior analyst gave us the idea of PS4.

Mr.Pachter said that US $399 could be the right price for PS4, however it can be more and most probably it will not be less than this because Sony will take a loss after they did with PS3.

Another analyst Mr.Pidgeon guess that, this business model is to lose the money so the price of PS4 could be US $450, but he is expected less than this.
