In response to the OP. I think it's unlikely. Possible but unlikely. I'd think that would involved the added expensive of a new design, though they may have already been working on such a thing in order to find the optimal size for the iphone 6 and 6 plus. That said, Apple tends to keep designs for a little while. They won't want to utterly cannibalized tablets. I'm guessing the market for giant phones is much smaller and that may be a deterrent. Especially given they have a ipad mini in the same range. One thing Jobs did when he returned was streamline their product offering and not have too much overlap. Now I think Cook may not really be making the same decision as Jobs would but i also think he probably doesn't want too many products to muddy the brand and the price points and give consumers too much choice to be confused with. Were I a betting man, oh I am. Never mind. If i was to guess I'd guess that the next few updates will focus more on software, spec bumps and if they are lucky maybe some genius new features or accessories. Off the top of my head i'd think Beats would be a big thing they could focus on. I know the geek crowd hates them. Doesn't really change things. Those headphones make that department self sufficient. I can see Apple coming on stage announcing a new Itunes radio which is basically beats and itunes radio slammed together. I could see maybe upgraded bluetooth beats pills. They have the new health app and maybe they want more accessories for it, integrating it with the Apple watch. I don't know but my gut thinks that the next Iphone will be more about adding software features and tweaking things.
