A report from earlier this week suggested that Apple (AAPL) panel supplier AU Optronics is currently developing the new Retina display for the company’s upcoming second-generation iPad mini. Now, photos of the next-gen iPad mini case may have leaked for the first time, revealing a sleek slate that unsurprisingly bears a striking resemblance to the current model. A user on Chinese-language WeiPhone published the images on Thursday, and they show a rear shell that is similar to the first iPad mini’s casing but perhaps slightly thicker to accommodate the Retina display. No other details were provided, but additional images of the possible new iPad mini case follow below.
