I am confused with the new Moto X4. Do we assume all three US versions will not be getting the same software updates? From what I can see there will be 3 variations of the X4 in the US- Amazon Prime X4, Project Fi/Android One X4 and Unlocked X4. Will the Project Fi version be the only version that will get routine updates from Google? or can we assume the Amazon and/or the Unlocked version will too? Has Moto been clear about the software upgrade paths for the various models?
