Prediction: I think developers will find a harder time to differentiate than previous iOS versions, and will feel a bit marginalized as apps evolve around a common style, palette and pattern. However, the user experience will be evolutionary.

Frankly, I feel that this design strategy has a split personality.

As I wrote in my past blog(http://mattzlw.wordpress.com/2013/07/24/ios-7-beta-ux-thinki...): "Making users think which part of the iOS application I am in less, instead, a more strong feeling in one single place Apple provides." Apple made their move. Whether the rebalance can be reasonably achieved or not, how and when remain uncertain. I do think, in terms of graphic design choices, it seems to have fewer variables. But, perhaps this is where a more dynamic 2D physics UI engine comes to help.

I agree.
