Mark Cerny: "they know how to design PS4 so it won't overheat"

The vents arent just at the back, theyre also in the middle of the console around the sides.

In all honesty, with the size of the machine I fully expected a power brick. If the launch consoles have heat problems, then I expect them to release a new SKU that comes with a brick.

One of the reasons why I aint getting one at launch really.
