Oh well though, it still seems the PS3 will continue to close the gap weekly, yet it wont reach 10 mil before the 360 hits 17 mil anymore |
Shipping numbers by the companies for one. From shipping numbers you can estimate remaining stock, and therfore sales more accurately then you can NPD. The problem is... you have to wait.
Then you have the fact that NPD does nothing with Europe or Japan. And that NPD has been off recently vs said shipping numbers.
Who by the way often offers corrections and retractions that the populace never sees. (I believe anyway)
Therefore if you add up every monthly released numbers they would almost certainly not equal NPD's actual end of year numbers.
