MacStories linked to this post over in The Verge’s forums, in which “gizmosachin” mocked up what (s)he thinks iOS 6 might look like.
All in all, I like the look. I agree with Marco that the blue default look within iOS and apps is dated. It’s time for a change, and I think the silver look used in the WWDC 2012 app is a great candidate for something new.
While I initially thought that June would be too early for an iOS 6 preview, if something as basic as UIKit is going to be updated, I expect Scott Forstall to be on stage at some point during the company’s keynote.
