From the naming of each generation of the iPads, I am thinking that Apple knew they were going to kill the 3rd generation iPad as soon as possible. The iPhones have followed a logical numbering system (3G - 3GS - 4 - 4S - 5), but the iPads have not (2 - "New" - "with Retina display"). With this type of naming, it seems as though the iPad 3 (as we call it) was the minor refresh in anticipation of the major upgrade of the iPad 4. The Apple store now sells three iPads (Mini, 2, and "with Retina display") and the iPad 3 is no where to be found. It is as if it was only a placeholder for the iPad 4. Maybe I am reading too much into the names of Apple products, but if visiting this site has taught me anything, it's that clues about upcoming Apple products come in many shapes and sizes.
