Years go by and people refuse to understand how quarterly reports are the only oficial and accurated (unless we are talking about Toshiba) numbers we can get.
We don´t need to know exactly how many devices were shipped.
Look at another Apple record breaking quarter:
"The consensus among analysts was that Apple would sell around 4 million Apple watches during this quarter. But given the wide range of prices on different models of the Apple Watch, and the fact that revenue is lumped into a larger bucket that includes sales of devices like the iPod, Apple TV, and Beats hardware, it is difficult if not impossible to work out exactly how many were sold."

It´s just how things works.
But any way, the 360 is a beast selling 10mi units since the One and PS4 launch...
