Marco Arment has an insightful and thought-provoking post on what iOS 7 could mean for developers. Go and read it here, it's well worth the five minutes it will take you.
Long story short -- we can expect some interesting dynamics in the upcoming months. Everybody will have to change their app to look and feel right in iOS 7 and this is not going to be an easy task. Especially if you are big and established. Especially if you have to keep iOS 6 (and 5 and maybe even 4.3) compatibility. So there will be an immense opportunity for new and small developers to pop up with apps that look great and polished on iOS 7.
Thinking.
