The hype train is adding new cars every day. Yesterday, an image was posted online of an early prototype of a PS4 controller. Recently rumors have been been pointing at the next iteration of the Playstation controller having a touch screen pad in the middle of the controller. The first image (shown below) fits the description of the leaks, and has been confirmed by multiple unnamed sources.
The second image released online today is a picture of the same controller shown above, so it seems that this may very well be the PS4 controller. As the Playstation event on February 20th edges ever closer, expect to see more leaks like this in the coming days.
