According to NPD Group, in the July 09 edition of Gamepro, it clearly states that Wii has sold 54 million, Xbox 360 has sold 30 million and PlayStation 3 has sold 22 million so why are the numbers on VGChartz saying that Wii has sold 51 million and Xbox 360 has sold 31 million? The PS3 numbers are correct though. I know it could be some adjustment but I don't think so. I think its a mistake because having a difference of 3 million can't be adjustment. 

I don't know how to post the picture directly on the thread so I have posted it in My Photos so visit my profile and then go to my photos and you will see the picture there. The numbers are in the bottom left hand corner.

So I hope someone on VGChartz can fix this.

lol, you didn't post any pictures in your photo album either. As a FYI the photo album has been broken forever, but it will work properly if you use FireFox even though it will tell you it didn't work.

@Wiii master

The nintendo and 360 numbers are from there latest quarterly update on shipments, the ps3 number is from december shipments from sony.

Vgchartz tracks consumer sales not shipped figures

There always adjustments so they are correct as possible.

@leo-j i don't get what you are trying to say and sorry about the picture i cant post on picture album just like nordlead said so i am going to try using firefox

is this what u mean:
that NPD Group provides shipped consoles while VGChartz provides sold consoles cause i dont know about that cause the magazine said By The Numbers and then below it said Results Provided by NPD group and then below it said Life-to-date worldwide console sales notice the word sales.... and then below that were the numbers....

without seeing what you are talking about, I'd guess that leo-j is correct. NPD only does American sales, and you are quoting world wide sales, which NPD doesn't provide.

Nope. The only one of those three figures that comes close to the last released shipment figures (which are all for the same date by the way) are the X360 ones.
The end of March shipment LTD figures were:
Wii - 50.39 mil
360 - 30.20 mil
PS3 - 22.73 mil

This is NPD, they don't state shipped figures... but don't actually track worldwide figures either,... I believe I remember a partnership between them and GfK though to release certain figures every so often.... it is possible that is what these figures are (added to Media Create or Famitsu as well) but the Wii figure seems high for it to be this.... it would make sense that it was the most over-represented compared to VGC because I think the NPD/GfK partnership thing would only include Western Europe/Aus and not Eastern Europe/Asian countries where the Wii is barely released, or if it is released, doing poorly compared to PS3 and 360 anyway. But I don't think it would account to that much.

No... leo is wrong, NPD do not release shipped figures, only sales.... but they only track the USA (and Canada but they are usualy released seperately) so in reality if NPD did release worldwide figures it could only be if they added their own numbers to that of GfK (Europe/Australia) and Media Create or Famitsu (who track Japan)

I suspect there has been a mistake somewhere though, as the 54 millon Wii number seems very high... it's possible VGChartz has been undertracking it but I don't think by that much.

Interesting thing is NPD's numbers quoted above mean Wii has 51% marketshare. :)

quick, time to change the numbers on the front page

They probably just took a stab at guessing shipment figures through June 2009 and messed up big time. Wii may be at 54 million shipped as of today (July 15), but I don't think it is there through June 30, 2009. The 360 and PS3 figures conversely are low for shipment figures through June 2009.
