Does anyone see the Android influence on iOS 7?
There's a lot of borrowing for all over the place. When I first saw some of the pictures it reminded me of WebOS, especially the card-based multi-tasking. The notification stuff is similar to Android, but it was already that way, and they did move towards a flatter design style a la Windows Phone.
Not really sure where they got the flamboyant color choice from, but someone mentioned that kind of color scheme is really popular in Asian countries, so if they want to target the market there to a larger degree it may explain it.
I think it still needs some time to bake though. The design has some nice ideas and concepts behind it, but it needs more time to evolve. They probably didn't announce all of the new features yet since the new hardware is still a few months away, so there may still be a few surprises.
