Blizzard claims 3.5 millions D2 sales on day one, VGchartz 1.8 mill on the week..

[Ail]

Weekly D3 sales are 6.3 millions units according to Blizzard again...

 

So VGChartz is 350% off...

I think this clearly demonstrate that the site shoudn't try to give PC software sales because the number have no relations with reality...

PS : the Blizzard number do not include the 1.2 millions copies they gave to Wow users that signed a 1 year subscription...

Here is the Blizzard press release :
