Apple is much more of a visionary than Samsung, and competing on that screen size is not what Apple is all about. Without meaningful hardware upgrade that will somehow work with their software (incl. cloud) to revolutionize something, there is no point in redesigning the case and including a slightly bigger (albeit technically inferior because it's of the same resolution so the dpi is lower) just so that fan boys can say Wow. Apple's revolutionary products are always led by innovation in user input, be it the mouse, click wheel or multi touch. The voice based input, and the NFC in the future, are truly the things that will make Apple shine. Until Apple can economically integrate LTE and NFC into a redesigned phone of the same or higher industrial design quality of iPhone 4, I do not see why Apple should try to make the same phone thinner with a larger screen. That's not revolutionary enough for Apple to even bother redesigning. I will be really happy and will buy on day one if Apple comes up with the 4S on Tuesday, and keeping the same design as the iPhone 4. It will send out a signal that Apple understands what this smartphone business is really about.
