Apple prepping a 4" metal iPhone 7c with A9 chipset, tips analyst, to be released in 2016

So far, he has accurately predicted that the rumored new 4" iPhone, dubbed tentatively the 6c so far, won't be unveiled together with the iPhone 6s and 6s Plus, but rather will make an appearance next year. If you have been following mobile-related news for the past year or so, there has been rampant speculation from many sources that Apple is probing a resurrection of the 4" screen diagonal, just not in the form of the "unapologetically plastic" iPhone 5c.
A 4" iPhone 7c would capitalize on latent demand for smaller iPhones
In a note to investors who subscribe to his research, Ming-Chi Kuo has now fleshed out that rumor quite a bit more, saying that a 4" iPhone will be put in mass production in the first half of 2016, likely to be unveiled in the usual fall timeframe, together with the eventual iPhone 7. The iPhone 7c, or whatever it gets named, will apparently be housed in a metal unibody, and sport Apple's current A9 chipset, which at the time of unveiling will be a generation behind the future A10. It's not the first time we are hearing that Apple's upcoming small iPhone will be crafted out of metal, too.source: AppleInsider
