According to AppleInsider, BrightWire and their sources strongly believe that Taiwanese Apple suppliers is working on second generation of 7.9-inch iPad mini. It should be included 2,048 by 15,36 pixels which is four times more than current iPad mini. If it is true that it will add 2,048 by 15,36 pixels, it will make much senses to have retina display as larger iPad. Current iPad mini has same resolution as iPad 2 as you can see in the left side of the picture. The right side of the picture is displaying iPad 4th generation should be same for next second generation of iPad mini.
