First, I can't make your link work. May just be me though.
I checked some other data though (googling, may have found the wrong things), and it seems to me that it is a MS press release, could it be shipped somehow?
Either way, it cannot be a lot. Microsoft said a few weeks ago now that they have shipped over 7M in Europe. VGChartz currently has it at 7.3M, which makes sense considering that this is just 1 week of sales above what they had shipped a few weeks ago.
I don't see the 360 being overtracked by more than tops 100K in Europe.
Thus, we must have either been undertracking the 360 up untill now, or the comparison with the GFK data is flawed somehow.
