Let's all remember: We haven't seen the PlayStation 4 yet. Along with games that were purportedly running on the system specs, Sony's event last month only showed viewers the controller.
So it's still up for grabs as to what the actual console will look like. That means that renders like the one above are still fair game. This vision of a would-be PS4... it's boxy. Can we get some curves up in there, Sony?
