So far it appears to be a very interesting piece of hardware displayed. Even the controller (Which is only displayed on one pic & barely noticable due to the color scheme) looks interesting as well. Rather this is real or not, I suppose we'll have to wait and see what Sony officially announces for PS4 when the time comes.
The laws of thermodynamics are in tears, they won't come out of their room. I tried telling them maybe there's a reason other than pretending to save power that the system is doing that, but they won't listen. And honestly, I can't imagine what that other reason would be.
