I'm amazed by the sizing. The SE appears to be gone. This means the smallest device you can buy is the 7/8. Many still find this to be too large. Considering Apple's history of selling older iPhone models at a lower price, it seems like two years from now the bottom of the line will be the Xs and Xr announced today. The smallest lower-end iPhone available at that time would be the Xs which is larger than the 6/6s/7/8…
The reason I don't totally discount the SE is the effective lowering of prices by Apple in the new line-up. They clearly want to grow on the lower end of the price band now.
