One of the anti-high-res-display arguments is that the 2x-res icons are being placed there in anticipation of an eventual "Retina Display" iPad 3. Why would software decisions about iPad 3 be made now? Using this logic, we should have found Mac App Store references in Leopard. I thus believe that we will see a retina-level display in the next iPad.
