Doubt we'll be seeing any major change like that at least until iOS8. For iOS7 it seems too soon. We might also see it in Mac OS XI, but I also doubt that's coming until 2014.
iTunes 11 is obviously not free of skeuo. There is at least the brushed metal volume knob and the pseudo-LCD display. I don't see how the new iTunes went away from the old iTunes, skeuo-wise, apart from the less-but-still-skeuo-looking LCD display.
