The only number companies can be 100% sure are shipped numbers.
Sony shipped no more than 4,3mi units, that is the only and final hard data we have from last December. And that is cloudy because Sony bundled PS3 shippments along PS4s.
When a unit gets to the retail the manufactors have little to no way to track its day-to-day sales.
They do a very similar job as VGChartz or NPD. Might be that they receve some directly retail reports (and that´s is may be why Sony UK knows how much ahead they are from Microsoft there).
