I just read a rumor saying that the new phones may not have 3D Touch. Although I don’t use all the 3D Touch features, I did use it enough to not be too happy if the new phones don’t have it. Might be another reason I skip out this year lol.
Most of the credible rumors suggest there will be three phones, and most of them suggest that one of them will be a cheaper, LCD, 6.1" model, and I believe it will be only that model (which I believe is likely the successor to the SE, despite the size) that will not have 3D Touch (just as the SE does not have it). I would bet that if there truly are two OLED models, they will have 3D Touch.
