Well, its official: the iPhone 6 will not have a larger display. For a 4.7 screen, it would need a 555 PPI. If Samsung could not increase their PPI beyond 441 for the S5, in fact they even lowered it by a little (and lets not forget they design and manufacture their own screens, thereby lowering component costs), then Apple will certainly not be able to do so while keeping their high profit margins on their flagship product. I guess well have to put up with the 4 size for at least the next 2 years...
Um, and why exactly 'must' Apple double the resolution again in order to increase the display size? They don't have to, you know. They could move to a new resolution thats more common, like 1080. So long as they keep the aspect ratio 16:9 (which they no doubt will), current apps could scale up to the larger display just fine and still maintain a PPI on-par with the iPad Air, while reworked apps will probably take very little time using new APIs in iOS 7.
And if you've been seeing what Apples been doing in iOS 7 and how they're actively encouraging developers to adopt AutoLayout, its fairly safe to say Apple wants developers to adopt AutoLayout so apps are more resolution/screen-independent.
