^Ah..but that's was very simple to do my friend. You see, every 80GB PS3 was bundled with Motorstorm (in Americas). So if you know how many 80GB PS3 are sold for a given week, or at least a very approximate ratio of 80GB vs 40GB PS3s sold, you can accurately estimate how many copies the bundled Motorstorm was selling.
But GT5:P bundle is a little different. GT5P is bundled with a 40GB PS3, and ALL PS3 sold in Europe are 40GB non-BC version (60GB production was discontinued, and they haven't got the 80GB one). But not all PS3s in Europe are GT5P bundles. So, how do you know how many of the PS3 sold in Europe are GT5P bundles?
