Good points, a lot to think about. And I do agree it seems like there is a long way to go before we are seeing many great apps in iOS 7 design language.
Original iOS may feel bland now, but I feel like the design language that it created bred extremely usable apps at a far higher rate than any other OS before it. I can't say that I see the same happening with iOS 7. The foundation just doesn't seem to inspire great design as easily. In the hands of great designers, we'll be fine. But let's be honest, the vast majority of all apps and even a large portion of those we use daily are not created by great designers (or are held down by corporate interests).
