Console makers *always* give numbers that are shipped to retailers such as Wal-Mart/Best Buy/GameStop, but VGChartz tracks sold to consumers. That means me and you. So Microsoft has shipped 17.7 million units to retailers, but only ~17.45 have been bought, so ~250k units are sitting on shelves. |
Most of the time they say units sold to stores, but, not always. Here are a few of the ways they can estimate installed base:
There are several ways they can know.
1. Purchase or use free data from NPD or data from vgchartz
2. Count registration cards
3. Count online consoles that called home
