I am not sure where you get that 1.5 Billion number from, I don't see Horace mentioning it. But the latest number of Active Devices, as Tim Cook mentioned a 100M increase would equate to 1.4B Active Devices. ( Which is actually slower than previous momentum, as they were adding 150M / year between 2016 and 2017. )

You are correct, the most recent confirmed number is 1.4 billion active devices. I misread the projection.
