The last few days have been very dry in the Apple-sphere with not much going on, be it in terms of 'Apple is doomed' news or on new groundbreaking Apple product rumors. But today a couple of "not so new" rumors popped up. But the interesting part about these iPhone 6 rumors are that they are from the Wall Street Journal, which has a reasonable record in the past of leaking Apple's yet to be announced plans. This time, the WSJ (via 9to5mac as you need to subscribe to read WSJ yourself!) reported that only the high end models of the iPhone 6 will have a sapphire display and these models will include both the 4.7" and the 5.5" sizes of the iPhone 6. So in spite of not so much news being leaked out about the 5.5" iPhone 6 (at least not as much as the 4.7" one), the report goes on to say that both the sizes of iPhone 6 will have the sapphire display in their high end models. But more interestingly for me, if this is true, then Apple's iPhone pricing strategy would see a dramatic change starting with iPhone 6.
Currently Apple sells a current generation iPhone and a older generation iPhone (iPhone 5C is still based on iPhone 5 for most of the part) and then within each generation iPhone, it sells different memory iPhone models at $100 more per piece. So the only high end model within the same generation iPhone 5S model that you can get is twice the memory for more money. But if this rumor happens to be true then, Apple is helping its higher end model/models stand out further by making them more feature rich, like a much better scratch resistant sapphire screen (that obviously costs more to make). This seems similar to what Apple did initially when its introduced Retina displays on its MacBooks, where only the high end MacBook Pros (started with the 15" ones and then descended to the 13" models later) had this "new" feature and they costed more. Of course with laptops the bigger the screen, the more higher end the model is. Now as I have quipped before, no one knows what Apple has in mind for the two sizes of the iPhone 6, as in which would be more high end? So either way as per this rumor, customers might have more choices to make and Apple might have more ways of differentiating its iPhone models and hence more ways to increase its profit margins (remember the profit margins for Apple are way higher for the 64GB iPhone 5S than for the 16GB one, see this nice iMore article for some details on this).
