They report that aside from one minor cosmetic difference it looks identical to the current iPad Mini, and that presents something of a problem. Since they don't show us the interior for all we know this is could be a current iPad Mini with a production quirk.
But if this really is the new iPad Mini then it probably means that it will have a Retina display if or when it is revealed next week. Assuming Apple follows their past behavior then the screen resolution will be 2048 x 1536.
That will give the new iPad Mini one of the sharpest 7" (ish) screens on the market with a resolution of 326 dpi. That will compare well with the current Nexus 7, whose 1200x1920 screen resolution offers a 323 dpi.
