It is still pixel perfect. Graphics is not up-sampled because it is still the same Retina tech, and black bars are mere inconvenience, I don't think it will be anywhere near as bad as indeed old 1x graphics in 3gs->4 transition. As for android team, Google's YouTube app on Google's Nexus 7 device with Google's Android OS, when launched in portrait, goes to landscape _automatically_ and takes button controls like back button from the bottom of the screen to the side. I truly believe that technology is there, but apparently nobody gives a flying fuck about it.
