Apple's iPad mini has been on the market for what, six days, and already rumors of its sequel are hitting airwaves. Not entirely unusual for the Apple universe, I suppose, but the mini hasn't even had time to breathe and already something better is being talked about.

According to DoNews, manufacturers are already in the early stages of producing iPad mini Retina displays. One supplier in particular, AU Optronics, which supplies the 7.9-inch panels for the current mini, is working on 2048 x 1536 displays for the next gen model. The boost in resolution would put it on par with the iPad 3 and iPad 4, meaning the mini 2 (or whatever it'll be called) will run all the apps already optimized for the Retina displays.

In addition to the higher res screen, AU Optronics will reportedly utilize Sharp's IGZO technology, which will allow Apple to implement an even thinner display while being more power efficient. The upgraded device will allegedly hit mass production during Q2 or next year in time for a fall 2013 release. I wonder what other sort of upgrades we can expect? A6X chip? 8-megapixel camera?
