I like seeing this contradictory data from VGchartz.  There is a reason why the gaming industry really doesn't take much credence in the numbers that come out of this site as it generally undertracks many games/consoles compared to what the actual sales numbers are.   If they were accurate, you would see this site tagged far more often when it comes to news about sales and the tracking that they do.  

I'm not ragging about these numbers as they are still strong, but honestly I take any and all numbers with a huge grain of salt as there are major retailers that this site "estimates" on some secret forumula as to what they sold, which is off more than not.  I'd trust whatever numbers the NPD or Sony/MS/Nintendo give out.

Similar to how they try to dissect Move sales numbers compared to Kinect. There has been a bias against Sony on this site and has been for years. 

Personally, I don't really care much about how much a game sells just as long as it's a good game.  Same goes for a console. 

Preview was obviously wrong then wasn't it.

no, it's not obviously wrong, i think we can't expect VGC numbers to be always perfect, can we?

I know japan preview is.

but for WW who knows?  we might get another out of no where adjustments after official report by PD or Sony.

I wouldn't be surprised GT5 strongest region is EMEAA where VGC has hard time tracking ps3 in certain regions.

Kaz and GT5 are sooooooooooooooo fast and with the Delorean in the Game they turned back on time and de-printed or de-saled the game by 400k more or less...

That or the numbers were wrong

It sold 2 million in 4 days, not a week. This week's chart ends on the 27th, no ?

Oh yeah and I suppose all Sony games are undertracked while all MS and Nintendo games are overtracked.

And if you didnt understand why they counted Move userbase instead of move units sold then you obviously don't know how the industry's working. Who cares if there is more than 180 million wiimote sold? Thats the same for Move.

Oh yeah and GT5 sold 2.07M first week, not 2.4M.

It is much more likely that the preview was wrong. ioi got more data as the week went on meaning the latest numbers are more likely to be accurate than the first estimates.
