The site says it expects the new devices to be called the iPhone XS, following the "S" naming convention Apple has previously used during years it upgrades the internal specs of the phones without giving the devices any major makeovers.

The new iPhones in the images are similar in appearance to the iPhone X announced last year, complete with a "notch" along the top of the display for the phone's front camera and Face ID sensors. New: A larger, potentially "plus" model that will have a 6.5-inch screen to go along with the updated 5.8-inch model.
