A second photo of the supposed PlayStation 4 controller prototype has popped up on the GameTrailers Forum.
The picture shows the same DualShock-style controller from a slightly different angle. While the controller is a bit larger in scale in this picture, it's still difficult to ascertain any new details about the controller beyond what's been discussed already. Based on this picture, the grips seem a bit wider than on the PS3 controller, and it looks like there's a jack at the bottom middle of the controller, possibly for headphones. Unfortunately, the jack, like the rumored motion control bar on top of the controller, seems awkwardly placed.
As for the source, posting user "SquishyMuffin" is keeping his or her mouth shut about the situation: They aren't saying who they are, where they took the photo, or how they even had access to the controller in the first place.
Obviously, this is all conjecture until Sony actually steps forward and confirms that this will be the new model controller. We're hoping, if not expecting, that we'll find out soon enough at Sony's upcoming PlayStation press conference on Wednesday.
