Recently today, another picture was added of the rumored PS4 controller. A few days ago the same controller was also posted on a website. In this picture, you can clearly see a 3.5mm audio jack on the controller. Sources from IGN and other highly trusted sites confirm that the two pictures that have been posted are real. The Analog sticks are shaped different from the regular PS3 controller we have now. It might have some modified features to it, that we have yet to know about. One of the new features you can also see is the blue light at the top of the picture.
Currently as of now, the controller has not yet been confirmed by Sony themselves. Some websites believe that it may just be another prototype they have been testing out. We should hear more from Sony as we get closer to the new arrival of the PS4.
