These are concept images, yes?
While I think this console is going to go the way of other systems that aren't the big three (like the 3DO, CD-i, and the Amiga CD32), I do think there could be some...potential with that center screen on the controller, but it depends on what exactly it is. Is it a touchscreen? Will it have tracking capabilities? How user-customizable will it be?
Depending on what it is, it could have some functionality that the PS4's trackpad doesn't.
That being said, I still await the day we have a mainstream wireless controller with six face buttons with all of the benefits of a modern controller. As much as I love my Fighting Commander Pro's from HORI, they can't be used for every game. And I still think that the ultimate controller would be one that's modular to be as customizable as possible. Like, you know how pre-built PCs are looked down upon in the PC gaming community due to their past and current reputation (looks at Alienware, Cyberpower, Corsair's gaming PCs, etc..)? I think it'd be neat if someone made a controller that could be multi-functional depending on how many expansions and modules you put onto it, making it the most cost effective and expensive controller at the same time, except that the users get to decide what they want.
I think about too many things while driving to college while I wish I could just take online classes.

You know, I've always been curious as to what they were trying to do with this controller. Like, did it have something to do with Sony's failed plans on integrating motion controls onto the main controller for the system before they came out with the Playstation MOVE, which, while it had better tracking than the Wiimotes from what I've heard, was too little, too late.
