Yes, it was a joke. inspired by xbox fans who were celebrating how Scorpio has outsold PS4 Pro because it was ahead of it on Amazon.
They didn't realize that it also meant that if Amazon rankings were correctly representing the numbers then it also means that XB1S couldn't have sold more than a few 100k units in all of 2017.
Haha 😂 ya these charts are cool but you can never make 1:1 connections. There's always tons of variables.
Halo MCC will sell 5+ million copies(including digital)
halo 5 will sell 10 million copies(including digital)
x1 will pass ps4 in USA, and UK.
