How is VGChartz going to keep track of Warhawk sales?

[Bonafide732]

as i said before it will be real hard for this site to track sales for warhawk .. socom .. littlebigplanet.. and other psn games... there should be some kind of system in place where lets say warhawk sells 125,000 its first week or day or whatever.. we should be able to add 5% or 10% or whatever % to account for psn sales.. i think it would be beneficial for sony to release the sales numbers but you cant believe sony's numbers though because they'll probably twist it..
