Samsung's plan all along. They got the maximum value out of their patent infringement, and it helped them rise to the top of the Android pile. By the time the case made it way through the courts, it was too late for an injection to do anything. This is the game, and Samsung knows how to play it.
Die shrinkage? Shaving off a few nanometers is insane! I think we should be very concerned about Apple's obsession with portability and power efficiency. They should be putting in more kitchen sink features and making the iPhone bigger, less portable, and more power hungry like the competition. /s
Have you compared the PCB of the existing 4" model to the alleged iPhone 6 (4.7" and 5.5")? I'm not sure how 2mm of thickness translates into room to "fit everything." You would either add more chips to the PCB, or integrate more functions into fewer chips. Either way, I don't see how 2mm of extra bulk adds room for "everything".
