I agree about the date, but I do believe they will make it with an edge-to-edge screen, because that's the way the market is moving, and they can't wait 3,5 years to do that, assuming they keep the same update timing.My head says that it’s likely the new SE will be a shrunken down iPhone 7/8/SE hybrid, which prioritises cost, released in March 2019:
- A11 processor and camera
- The screen from the 7
- no 3D Touch
- physical home button (Taptic Engine is huge and would surely be tough for Apple to fit into the 4 inch phone. Us I think they’ll try and make the battery as big as possible.
- no headphone jack (waterproofing & to fit in a larger battery)
- dual speakers (if they can fit them in)
