Thought it was odd that Sony didn't show off the PS4 at... a PS4 reveal? Well, you're not alone! It was odd. But it was also understandable, seeing as how, you know, Sony doesn't know what the final retail machine will look like, either.
In an interview after this week's unveiling, Hiroshi Kawano, President of Sony Computer Entertainment Japan, was asked by 4Gamer about the PS4's design. "If I'm being honest, I also haven't seen its final design. Even the controller we showed today, I saw the final design around yesterday or so."
That doesn't mean Kawano and other Sony brass have no clue what the PS4 will look like. Certainly, they've seen prototypes and mock-ups—just as they have for the hardware they revealed at this week's event.
About the PS4 controller, which was shown at the PS4 announcement, Kawano explains, "I've seen numerous prototypes from when it was still codenamed 'Jedai', and I heard that an onboard touch pad was in the final specs."
Add Kawano's comments to Sony Computer of America boss Jack Tretton's remarks that the "mass-production box" was "still in development in terms of final specs and design", and, yes, you can see why Sony didn't wheel out the PS4.
