Motorola has not produced a flagship for several years. The Moto Z3 was almost one, but the old processor inside left it among the cell phones of the competition. By 2019, they've been flooding the market with more midrange cell phones than I can track, giving us no signal that they may not stay on that lane for a while. As it turns out, they plan to re-enter the premium market in early 2020.
Motorola President Sergio Buniac spoke today at the Qualcomm Summit in Snapdragon, setting a vague schedule for the year ahead. The big news here is that Motorola is indeed planning to re-enter the premium market for smartphones and products, and not just the ultra-expensive Razr folding tire.
You will be using Qualcomm's 5G enhancements and (with an "S") beginning ("very early") 2020. I imagine we get a Snapdragon 865 phone But today Motorola has explicitly stated that they will certainly use the Snapdragon 765 to expand their 5G range around the world. They will also launch the fastest 5G phone that can reach over 5Gbps speed with Qualcomm's flagship platform.
