You all are forgetting the most important thing (no offense), this is VGChartz, this AREN'T official numbers, so you can "stop" looking for answers in their numbers.
The numbers aren't official, they don't track PC, they don't track downloads (steam, games on demand, a ton of other sites) and they don't track every store.
VGChartz shows statistics that they believe are close to the real thing. And I thank them for that, but in the future is going to be more and more inaccurate (downloads).....
