Playstation 4?

Altough the Playstation 3 is a phenomenal console, sometimes its just not good enough for some and they need new things when other things get old. So I am sure if you are a playstation fan you are wondering when is the Playstation 4 going to come out. It is being worked on over in japan but it is very slow creating it because if microsoft XBOX comes out with a new console then the Playstation has to be that bit better because if not they will be outsold. Personally i think that the new console will be mainly focusing on virtual gaming and improving Playstation network they mey also start working on 3D playstation gaming also. I and a lot of other have very high expectations. I can only imagine how great the console will be. Here are some estimated pictures of the Playstation 4.
