Well one thing I will say is that iOS 7-9 wouldn't work on an edge-to-edge screen due to the lack of bezels, while iOS 10 would, due to the presence of OS bezels. Just look at the Control Center.Ok, let me actually say something meaningful instead of being a smartass about it lol. If flying objects make you think the new devices will get edge to edge, then the iPhone should've had it 5 years ago, because iOS 5 and 6 had floating objects that were later changed in 7. The UI concept has technically gone a step backwards to iOS 6. Skeuomorphism is coming back quicker than you think. Anyways, I don't really think iOS 10 points to any hints of edge to edge at all. Just some redesigns here and there, and fixing (somewhat) what iOS 7-9 screwed up on. iOS 10 makes iOS 7-9 look like betas and alphas. 10 is definitely not as jam packed with features and overhauls as I though the 10th anniversary iOS would have, but its satisfying enough. Once again I don't see how floating objects hints at anything.
Still don't really care about edge to edge...

This is very true.Interesting thought indeed. Since someone mentioned why implement it now, take a look at 'swipe to go back', introduced in iOS 7 and talked about in the iPhone 6 (iOS 8) keynote, same for the iPad multitasking before iPad Pro was revealed.
