Looks like VGC have PS4 tracking down packed if you consider official recently released shipment figures, nice work guys.

It could be worse, since there are probably at least 1.5 million PS4 units on the shelves. So its probably a million units undertracked. It's hard to count PS4 units being sold outside Europe, North America and Japan.
