I just bought an iPod nano 7th gen and it's a convenient little device and does what it's supposed to do great (perhaps longer battery life would be nice), however it has many iOS 6 design elements, most notably in menus and in the music app. What are the chances of it getting a software update to bring the visual aesthetics closer to iOS 7 as far as menus, the music app, etc? I'm guessing slim to none because Apple is probably dedicating all of its resources to iOS 7 fixes and future OS's and products. Has any other iPod nano received aesthetic changes in a software update in the past?
