We can see based on Sony earnings release that VGChartz numbers are off by so much the data we have here on PS2 software sales is pretty much meaningless.
NPD doesn't actually do a much better job ( they are slightly better but still off by an order of magnitude at least().
In that light, does it make sense to list estimates total software sales when you know they are so much off ( maybe keep tracking top PS2 software sales but don't list total PS2 software sales for the week, those numbers are meaningless)....
