New photos posted at a Chinese site, WeiPhone, show what is supposedly the rear shell for a second-generation iPad mini. In most respects the shell appears to be similar to the one for the current iPad mini, except thicker; that may, however, be because the part has yet to be given chamfered edges. A thicker back could alternately support views that the next Mini will get a Retina display; when the third-generation iPad gained Retina support, it also became slightly bigger.
