I was just wondering, if apple had started off with a goal in mind, let's say it had already planned to support the iPhone 3GS and above when It started developing iOS 6. Perhaps the reason why apple deciding not to bring any dramatic user-interface changes was because it wanted to support the iPhone 3GS, which given the hardware limitations will be unable to handle. No way is Apple ever going to compromise on the usability of the system just to push out a new UI. In addition, if people like many of us here at the forums was expecting a UI change, it is highly unlikely that Apple had not considered this in the planning stages. Therefore I think that Apple may be deciding to push back the UI improvement to iOS 7 or later when it drops support for the 3GS & maybe the iPhone 4. IMO, only the newer hardware like the 4S & the new iPhone will be able to support this newly enhanced UI.
