Nintendo posted the freely published numbers in a later slide (where the quote is from). The numbers that are in the slide on this thread are from a combination of sources probably non-published & published numbers. ioi already stated why he adjusted the numbers, so obviously he believes that Nintendo is correctly portraying the private information in a way that will help this website estimate different region's marketshares better. @seece so if they (GFK etc...) aren't 100% right, why the crusade against VGChartz adjusting the numbers. obviously if none of them are right, then how can VGChartz be wrong? (obvious answer is by posting numbers that are higher than shipped, but this isn't the case) |
GfK (Gesellschaft für Konsumforschung) is a very large company that operates, like NPD, on the sales data they can get from distributors/shops (on _any_ consumer goods. If you want to know how many red bras were sold in country xy, you pay for the data..). In Switzerland, for example, they have the shop data for >95% of all consoles sold. So their numbers are extremely precise. In other countries, the mileage may vary. If you want the console data for Europe, you have to pay for it (probably a rather large sum at that). Occasionally a few GfK data points got spilled into the public domain (and usually showed that the 360/PS3 gap was much lower than shown here).
What I don't like with this specific adjustment are several questionable things:
a) Nintendo has an estimated graph of some (major) European countries. This site equates "Others" essentially with the entire PAL world.
b) ioi states corrections were over 3-4 years for some parts of his regional data (whatever they are) - so he now adds a single correction over a dozen quaterly financial reports from MS/Sony which already caused corrections when they were issued?
