Here, by giving the pattern of Apple's iPhone launches, Apple company are expecting the next-gen iPhone 5 release date to be mid to late 2012. It could possibly be shown off at Apple's Worldwide Developer Event (WWDC 2012), which usually takes place in early June even if the focus of the 2011 event was software but for this year event, it will be something new!! They also are expecting iOS 6 and more on OS X Mountain Lion this time around so it could be that hardware is further down the list again..
