iOS 7.1 reveals two new iPad models?

Apple’s new release of iOS 7.1 arrived with support for two new iPad models: iPad 4,3 and iPad 4,6, as noted by 9to5Mac. It’s unclear what these models represent at this point. The report speculates that the iPad models may be “minor hardware revisions,” or possibly optimized models for overseas networks; they appear to be continuations of the iPad Air and Retina iPad mini families.
