Problem with softwares's 360 sales ??

[Clanki]

Hello everyone.

I have a question :

I hear everywhere that XBOX 360 owners buy a lot of games . "Small hardware but very high softwares" " XBOX 360 owners are gamers: they buy more games than PS3 owners or Wii owners".

At the Microsoft's conference, I saw it about software :

But, seeing vgchartz, we can see that it's not the cas : 140 mil. (Wii) + 60 mil. (PS3) >>>> 131 mil. (360)

I work in a videogame shop in France and I sell more 360 games that PS3 games or Wii Games. ( I know my shop doesn't represent the world but it's an example ! lol )

So, is vgchartz undertracking the 360 software ??
