Assuming the rumors are true, the iPhone X will be roughly the size of an iPhone 7 with the screen size of an iPhone 7 Plus, what is the reason for the iPhone 7S and iPhone 7S Plus existing beyond price and availability? The iPhone X gives you the best of both the iPhone 7 and 7 Plus, the smaller footprint and the larger screen. I personally believe the iPhone X will start at $100 more than the base model iPhone 7 Plus (so $869) and I imagine Apple wants to offer new iPhone's this fall at a lower price point. (Hence the iPhone 7S and iPhone 7S Plus.) But price aside, I feel both phones are going to be a hard sell when you've got the iPhone X that everybody will truly want instead.
