I believe Vgcharts should start estimating and including digital sales. Right now sales of recent games don't make any sense and neither they represent actual sold units. Just look at Uncharted 4, God of War, etc we got exact official numbers but on Vgcharts they are still off.
Its time Vgcharts started estimating digital sales.
Digital sales should've been tracked years ago starting with Halo 5 or further.
