The Wall Street Journal also notes that Apple will not change the size of the screens on its next-gen smartphones, so they should come with 4.7-inch, and 5.5-inch displays, respectively. Moreover, the publication has it that - just as previously rumored - the upcoming iPhones will make use of Force Touch, a new technology that Apple is already using in its Watch and the latest MacBook. Thanks to Force Touch, the screen of the iPhone 6s will be able to differentiate light taps from hard presses, thus possibly offering new features that the current iPhones aren't capable of.
The Wall Street Journal further reports that mass production for some iPhone 6s components should start in May. Thus, we assume that, like in the previous years, Apple will announce its new iPhones in September.
P.S.: What you're seeing above is just a quick mockup we made based on the gold iPhone 6.
