On the subject of Sony's 10m announcement and adjustments and in an attempt to be fully transparent - until we can figure out where the "missing" 600k units have been sold then we obviously can't adjust the figures since they certainly aren't in the USA, Canada, Mexico and South America, UK, France, Germany, Spain, Italy, Benelux, Scandinavia, Eastern Europe, Russia, Australia, New Zealand or Japan in which our data is very accurate and lines up well with other data providers. Our estimates for the other regions (Middle East, Africa, Asia) are rough estimates based on trends seen with PS2 / PS3.

Our data for the regions we track as listed above for PS4 adds up to around 9.0m which should be accurate to +/- 100k. We estimate a further 140k in the Middle East and Africa and 290k in the remainder of Asia taking us to the 9.4m you can see on the homepage.

If Sony's numbers are to be believed as being accurate sell-through then clearly they have sold an enormously disproportional amount in one of those regions and once we know which one we can make the necessary adjustments. We can't just add 600k units to the total - we need to know which regions to adjust so we can ensure that we are on track moving forwards. This is why adjustments don't always happen straight away or sometimes not at all - we can't just randomly add sales here and there to make things add up!

The same goes for complaints about PS3 and 360 sales - until we can get hard data for regions such as the Middle East, Africa, Korea, Singapore, Hong Kong, India, China and so on then the best we can do is extrapolate based on general market trends and make best estimates for specific platform sales in those regions. If you wish to help and know of any reports or research in those regions then let me know and we can compare to our estimates and make adjustments as necessary.

Ok but you do know X360 is overtracked by 1M in Germany(official numbers from germany) no need to search where to put these numbers, and still, you didnt fix that.
And it's pretty clear PS4 undertracking coems from Europe, you undertracked it by 50k only in Germany, so it's easy to imagine it's the same in a lot of other countries in Europe where your datas are the less accurate.
