An iPhone 7s Plus and iPhone 8 walk into a bar, and the resulting fight is between the legacy Apple design that millions of people are accustomed to and don't want changed much (for example, having a home Touch ID button), and the future of the company's handsets. The iPhone 8 will allegedly prime Apple fans for what's coming down the pipe - edgeless OLED screen handsets with multiple cameras and 3D sensors ready for the AR era - while the 7s and 7s Plus will aim to make the transition smoother.
That's not to say that the 7s and 7s Plus won't get design upgrades - as you can see from the video above, comparing 7s Plus and iPhone 8 mockups, they will all have new glass backs to aid the alleged wireless charging pass through easier, and have much more understated antenna lines, plus shinier side bands. Overall, however, the star of the show this year will be the iPhone 8, and if you are hesitant about that, just have a looksie at the comparison above.
We don't know if the software solutions on both phones will also be different - Apple has to somehow accommodate the iPhone 8's screen 'notch' at the top, but, overall, the all-screen handset may have a different iOS 11 overlay, be it only for the alleged virtual buttons users will have to navigate with.
