If you needed further proof that these devices are in the works, the folks at 9to5Mac have spotted several iPhone model numbers registered with the Eurasian Economic Commission. This has been happening for quite a while now, where the model numbers are registered which later turn out to be the actual phones, so there is a good chance that these model numbers represent the three iPhone models rumored for 2019.
Unfortunately, apart from the model numbers, the filing did not reveal anything else. However, based on the rumors we have been hearing, Apple is expected to introduce a new camera design across all of its iPhone models. For its flagship models, Apple could be bumping up the number of cameras from two to three, while the iPhone XR2 is rumored to gain a second camera.
Take it with a grain of salt, but we expect that more details will probably be revealed in the coming months, and possibly within iOS 13.
