Personally (yes, my opinion) I agree that I would like to see changes and am hoping to see some of the things the concepts/mockups have put out there as well as what they haven't thought of. I really hope for something fresh, but not Android-like. And I don't think that is hard to do since there are other aspects of Android that are in my opinion awful and don't invite ease of use.That does look very nice. This time I'm really hoping to see some serious improvements to iOS. There are many short comings that need to be addressed.
Next year I expect to see a larger iPhone. Otherwise I could be switching after 6 years of owning iPhones.
