I have a 2012 MacBook Pro Retina and according to what I can find on the web, the early 2013 MacBook Pro Retinas have the roughly the same internals except for the cpu model number. Everything else is the same, so I'm not sure why Apple would cut off the 2012 MacBook Pro Retinas. Is there something I'm missing here?
