Aside from Ming-Chi Kuo (who has proven to have sources more than inside Apple's supply chain issues), the talk of analysts covering the world of Apple should be interpreted very moderately.
Blayne curtis, an analyst at Barclays, one who has no striking history. But it's still hard to hear what he supposedly heard from her (he and his associates recently took a serious trip and met with Apple vendors) about the company's future planning.
Some things are pretty much right and much commented on, such as maintaining the foundation of the current design, adding a third camera in the XS and XS Max successors, 4G RAM in the XR successor, etc.
Curtis, however, believes that 3D Touch should be completely eliminated from across the board (in favor of Haptic Feedback, which is present in the iPhone XR and would be expanded to all devices).
In addition to Samsung, LG may also become a provider of OLED displays for the 2019 iPhones (in a 10-30 ratio); In 2020, Curtis bets on the complete abandonment of LCD screens in favor of OLED ones.
For next year's models, the analyst believes we will have more significant changes, such as 5G support, “3D detection” through a rear camera system and a new technology for you to see. implemented on the entire screen of the device.
In addition, the analyst mentioned the possibility of Apple launching an "iPhone SE 2" with internal components of iPhone 8. This device could hit the market in 2020, but Curtis made it clear that only a few Apple vendors are aware of the issue. others have no idea and would not hear of this supposed release.
We'll see if the analyst's hit history gets better or worse after the 2019 and 2020 releases.
