The fact that certain companies don't make retractions completely skews how their data represents the marketplace. As consoles are shown to be selling certain amounts just to make up past mistakes instead of actually showing how many consoles were actually sold that week. Thus it becomes pretty difficult to spot trends and the data is essentially an exercise in fantasy. Retractions are a much needed response to incorrect data and its one of the best things about vgchartz.

 Wow, that's just retarded.

Well I guess you've been in the statistical business for at least 20 - 30 years...

No seriously, that's just retarded.  You know not what you talk about.  Please try to at least post something with truth behind it before you make yourself look silly.

//EDIT//

Just got updated that Kasz means The other way.  Sorry Dude.  I thought you where bagging out VGChartz for updating their data.

What I find more fun is nintendo was reporting 5.17 million for april may and june '08 and a total of 29.62 million. Taking the average 1.72 million per month it puts this site behind on wii by about 1,330,000.

of course that's assuming averages are kept up but wii still sells out in a good number of places so chances are it didn't suddenly drop by that amount..

it also assumes nintendo still reports on sold to end users and not retailers.

Shouldn`t be July 26th SOLD = ~ June 30th SHIPPED + 80GB bundles, since 40GB models are being nearly sold out in MANY places?

VGChartz and their adjustments...it's great because this should mean we can even have greater confidence in the data!

Now can we see some adjustments to Australian sales (I know only three people care) - the Wii just passed 500,000 and the X-Box was sitting at 416,000 around a month ago. Also Sony have just given away 35000 PS3 with Bravia here...but can these be counted as sales?

P.S - Sqrl I wish Leo-J wasn't banned just to see what he would saying right about now!

Way to take it out of context.  Kasz simply means for example that a company reports 600k for month 1, then during month 2 they realize they overtracked by 50k.  So instead of reporting 500k during month 2 they report 450k.  This company would be less trustworthy than a company that intially reports 600k for month 1, then adjusts the amount to 550k, and reports 500k for month 2.

VGC certainly does the latter, though it's up in the air as to how NPD handles corrections.  I'm inclined to believe that they do not adjust future months, but instead release corrections to paid customers only.

@souixan
Nintendo always has reported to retailers, it's just due to Wii's being nearly sold out WW for so long the numbers were very close.  Also, the difference in shipped and sold can most likely be attributed to the often proclaimed and also often denied stockpiling.

Good point, though retailers also do stockpiling. Though at this point of the year it'd be pretty pointless on their parts.

No, because USA <> TheWorld... there are still tons of (expensive blu-ray bundled) PS3 lying around here in Europe...

Also note that it is actually > 14.41 as the various Bravia givaways (68k in Australia alone) were never in the retailer distribution chain. Technically Sony "sold" more than 14.41 but we are talking in the 1% level so who cares...

Apparently ioi reduced the PS3 numbers downwards, feeling his sold was too close to shipped. Strangely he didn't do it with the X360 numbers although the same problem exists there (sold too close to shipped). I'd guess that for any console roughly 600-800k units are in transit anywhere (in transit meaning sold/not yet sold, on shelves/in shipping containers(wherever).
