The leaked pictures don’t really show anything else new. The same round cutout for the home button is there and a front facing camera sits on top.
Apple device components have leaked out extensively over the last few weeks, and there is too much smoke for there not to be a fire. In other words, it seems likely that all those rumors have something to do with the reality of the situation and Apple is indeed preparing a massive refresh of its whole mobile portfolio this fall.
Apple is expected to unveil a new iPhone or iPhones (the iPhone 5S and the plastic iPhone 5C) on September 10th, and expectations are that a new iPad and iPad mini will launch in time for the Holiday shopping season.
