If you look at the full-size images at Gizmodo the entire side metal area all the way around sticks out from the flush casing pretty noticeably. I think it's a prototype case or some kind of unfinished disguise. I forget where Ive was interviewed (perhaps in Objectified?) but he mentioned how much he stresses over the tightness of two joints and how perfectly flush he always wants them to be. I'd really be surprised if this were the final design, I'd guess that the top and bottom are final versions but the side wrapper will be a unibody-style, fully aluminum case.
