It is expected that Apple will be launching several new iPhone SKUs this year. Their new 2018 lineup of iPhones are rumored to have 5.8-inch, 6.1-inch, and a 6.5-inch screens based on a leak of the front panels.
All the SKUs on the 2018 iPhones might also have notches as well as OLED panels on the 5.8-inch and 6.5-inch variants. The 6.1-inch variant, however, might have a more traditional LED panel. The leaked front panels also minimal side bezels as well as ultra-thin bottom chins, which should lead to a more impressive body-to-screen ratio.
If these are indeed true front panels on the 2018 iPhones, then it seems Apple is sticking to their notched design instead of embracing all-screen displays seen in Android smartphones such as the OPPO Find X, Vivo NEX S, and the allegedly leaked front-panel of the Meizu 16 Plus.
