Nice! I hope this is indicating a new wallpaper, and a long shot, but perhaps the silver 6 means silver theme?
Think about it for a fast minute. If it really is the most advanced, then it doesn't try to play "catch up" with anyone else. Most people change stuff to impress someone, maybe Apple doesn't feel like it needs to. Just a thought! ;-)
Why change/fix something that is not broken and that consumers enjoy and/or can easily learn how to use.
