In case you hadn't realised there's a difference between the guys who design the inside of a console and the guys who design the outside, take a look at this tweet (via PlayStation) from PS4 lead architect and game development legend Mark Cerny.
Cerny: I hadn't actually seen the console until Monday's event. I wanted to wait and see it when the rest of the world did. It's beautiful

Sony took a lot of heat, much of it justified, when it unveiled a console back in February without actually unveiling a console. Sony said back then that designs were still being worked on; if Cerny somehow avoided seeing one until June, I guess they left it late to lock one down!
