I really don't know, but if we talk about undertracked all of the ones I listed above undertrack the PS3. Every single one. That does sound strange. But maybe Sony counts in a different way. Like consoles ordered, but not shipped or even sold to customer yet. This is no trolling, just some thoughts.

How often do we really get hard numbers from Gfk, and when we do, what countries do we get the numbers for?
And are there any major trackers for the Latin American markets?
Without these figures, we can't do a proper comparison. As far as I know, there's little to go on when saying VGChartz lines up with Gfk in some of the smaller/less tracked Others markets, and then there are markets (like the aforementioned Latin America) for which there are no official trackers that I know of.
