Other than the last one (which is possibly just the new desktop wallpaper) is pretty much what I was thinking. Everything else is very airy and light. Plus, the "7" in the banner is also multicoloured in the same hues as the rounded square icons. I think that has pretty much given away what iOS 7 will look like from a style choice point of view. At least, I hope it is. I quite like it!
