I think there is a lot of reason to speculate that FaceID will be completely replaced with an actual solution that Apple initially tried to implement which was TouchID embedded into the screen. I think they are testing the market for $1000 phone and are paying a high margin on the FaceID camera array. So I think their plan will be to replace it as soon as possible with technology that will give them a higher profit margin which TouchID in the screen certainly would. This means that the iPhone X2 will remove the notch completely and I think Apple will find an innovative new way to integrate the front facing camera while retaining the entire front as glass. So the next iPhone X will have a uniform screen. Just my thought.
