Xbox ONE is too damn high and way overtracked.
There is no way this console is over 16 million sold, let alone 20 million. sold.
The reason MS doesn't say anything about VGChart'z guesstimations is because their estimates look better than actual sales. You can bet that if the Xbone has sold even 1 unit higher than VGChartz's estimates, MS would at least acknowledge that VGC's numbers are inaccurate and they sold more units than what VGC estimates.
Their silence only leads me to believe the VGC is significantly overtracking the Xbone.
Lets just say I disagree and think this is borderline trolling.
