This years iPhones are expected to come in new sizes one with a 5.4-inch display, two with a 6.1-inch, and one with a much larger 6.7-inch screen.
Chatterjee suggested that in the year 2021, Apple will change the way it introduces new iPhones. Regardless of how many iPhones are released, the entire iPhone lineup is expected to use OLED displays and 5G technology. These devices will all - apparently - roll with 5G connectivity.
Rumors have suggested Apple is going to use Qualcomm's X55 modems in all of its 2020 iPhones, and while those modems do support both mmWave and sub-6GHz spectrum, an additional mmWave antenna is needed for mmWave support. Speaking of that product cycle, all of the new iPhone models mentioned above that are reportedly coming in 2020 would support 5G, while the two higher-end models will support "world-facing" 3D sensing, according to Chatterjee.
According to JPMorgan analyst Samik Chatterjee, we might be getting a lot of change in the way Apple releases the iPhone. Per a Marketwatch report about Chatterjee's forecast, the analyst thinks this shift in the release timing could help Apple "smooth seasonality" around new iPhone launches and to be in a better position to compete with offerings from rivals throughout the year.
Generally speaking, Apple now only launches new iPhone models once a year, with the new handsets landing in September.
What's most important here for non-iPhone sorts of people is the idea that Apple would be confident enough in the strength of 5G coverage for the upcoming release season that they'd include said tech in all of their next smartphones.
