| Nsanity said: I do remember one year that ethomaz was using this sites numbers instead of NPD for Killzone 3 because they were higher. |
Yeah... this time NPD made some errors in data and in the next month fixed that.
Anyway NPD before start to track Wallmart did that some times... show a number difference from what the PR said and the next month fix the number to match with PR.
Eg.
Apr: 100k consoles X with bundled release of new super game
May: 200k no release and no bundle
So NPD fixed their sales data in May for track wrong in Apr.
