5m is a great milestone, but it's not sales yet. So, it's not success yet.
Don't get me wrong, I bet it will be a success, but not quite yet. I want to see sales numbers, specially Japanese sales
God bless You.
My Total Sales prediction for PS4 by the end of 2021: 110m+
When PS4 will hit 100m consoles sold: Before Christmas 2019
There were three ravens sat on a tree / They were as blacke as they might be / The one of them said to his mate, Where shall we our breakfast take?
