What will the PS4 look like?

It can't look any worse then the Xbox one........surely?

Have you not seen Sony's previous attempts at console designs? Ugly slabs at launch eventually finessed into something smaller and less offensive.

That's the console manufacturer trick, make them abnormally large.
Not only is it cheaper and more reliable, but it also means to you sell people a new form factor in 3 years time.
