While all three models are expected to come with iPhone X-like designs, two of them are expected to sport OLED panels and will be priced on the higher side of things, while the 6.1-inch LCD iPhone will be the cheapest model and Kuo notes that Apple could sell around a 100 million units of them.
Unit growth in Apple's older iPhone models after the new models arrive could help soften the blow, too.
Kuos optimism comes following Apples recent earnings call where the company said it sold 77.3 million iPhones in 2017.More news: Here's how people reacted to Elizabeth Warren's speech

This year, Apple is expected to launch three new iPhone models - a direct successor to this year's premium iPhone X, a larger and even more expensive version of the successor to the iPhone X, and a lower-cost model with a less advanced liquid crystal display (LCD).
We know some hardcore iFans might be disappointed to hear this year's iOS 12 update is unlikely to bring many new bells and whistles to either iPhone X generation, but there's nearly no doubt Apple's decision to focus more on software stability and reliability is the right one. Being an iPhone user myself, there have been very rare instances when I opted to take advantage of 3D Touch, but I still do not believe that the feature is going to be omitted from future devices. That is, by analogy with X iPhone the new tablet will disappear and the traditional home button and bottom frame. According to Kuo, the third model will carry a 6.1-inch LCD screen and have only one camera on back. KGI expects it to make up around 50% of overall shipments, with the "new iPhone X" and "iPhone X Plus" (tentative names) making up the difference. On that basis, today's shipping estimate suggests lifetime sales of 2018 iPhones could reach approximately 200 million units. Apple sure does ship a lot of phones.
