Zac Hall, 9to5Mac:
Nikkei Asian Review is adding to recent reports that Apple will move to an all-glass design with the iPhone 8 next year, while reporting that the lineup will add a 5-inch model. Apple previously used an all-glass design with the iPhone 4 and iPhone 4s, but switched to aluminum backs with the iPhone 5 through iPhone 7. And a 5-inch iPhone 8 would add a new option to the current lineup which includes 4.7-inch and 5.5-inch flagship models.
I don’t know anything about this, but adding a third iPhone model makes no sense to me. Much like the rumoured 10.5-inch iPad, my guess is that this is a misinterpretation by a source or an analyst.
Ming-Chi Kuo claimed in March that Apple has been working on a 5.8-inch model, which is the same 0.3-inch difference as between the rumoured 5-inch model and the existing 4.7-inch model. My hunch, for what it’s worth, is that these rumours describe larger displays that sit within the same two case sizes as the existing lineup.
