I just found this PS4 fan 3D model and besides the "swipe" thing on top, I really like it.
Would love to see a PS3 redesign like this
I do like that render, and I do like the "corner" slot for the Blu-Ray drive, but it makes little sense both in terms of laying out the system internals (ie. mounting a drive diagonally like that), and it prevents you from putting the side with the slot up against the side of a TV cabinet because you need clearance to the right to get the CD in the right place.
As for the controller, maybe they finally wised up and bought the molds from Logitech for their wireless controller variant of the Dualshock:
I had the PS2 version and it was really comfortable. The face has enough extra room (compared to regular Dualshock) for the touchpad, and then they'd just have to modify the PS2 version for triggers (not sure if Logitech made a PS3 version with triggers or not).
