perhaps they got it directly from Microsoft, i mean are you really surprised that it is undertracked on vgchartz?

And why would Microsoft share that number with CNBC?

Daniel Ahmad mentioned that Xbox was at ~41M at the end of 2018. There's just no chance that Xbox has sold 6 million units so far this year. So it's definately not undertracked on VGchartz either.
