PS5 Games Console
The Sony PS5 Playstation isn't real. There is no PS5. The official word from Sony is no comment.
Whilst recent stories surrounding the PS4 do appear to be based on some reality, the PS5 is just wishful thinking at this stage. However, given that there has been a PS1,PS2 and PS3. And that the PS4 is likely to be released sometime in the next year or two. It seems quite probably that Sony will continue on this theme and release a PS5.
PS5 Games
Once Sony have released the PS5 Console, it will of course follow that they will release dedicated PS5 Games. Conceptionally, it seems quite feasible that if PS4 is all about 3D, PS5 could well be about virtual reality.
Combine this with mobile technology and social networking, and you start to evolve the concept into a 24/7 gaming world where we live, work and play via a constant realm of instant communication.
