I guess they've moved these down into the price slot. Retina has only been out since June. It'll probably take another year before everything is Retina.
Another thing to consider is that Apple just introduced AutoLayout in iOS. They will expect developers to have adopted that within a year or so, which will free them from the basic resolution doubling that they've been doing.
