| catofellow said: How many different PAL tracking firms are there? As Sony does not run their own tracking firm (hence they wouldn't know 360 sales for a period as short as 1 week) they must be viewing some 3rd party sales data. Are there any weekly charts that have PS3 at 3:1 vs. 360? If not it could be a lie, or a mistake. Also, of course if VGchartz if off GFK will be off too. VGchartz is set up to mirror other sales data like NPD, Famitsu, and GFK. |
VGchartz does not mirror other sales data. Ioi gathers sales data from his own sources and only uses other trackers to adjust his formula's.
