Vgchartz actually has all 3 games undertracked.
Uncharted: Naughty Dog said back in April that they shipped 17.3 million copies of Uncharted series. right now 9 months later, vgchartz has the sales for the Uncharted series at 17.1 million. so either sony still hasnt sold out of their shipment from 9 months ago or its undertracked. also it wasnt clear is ND was including Uncharted: Golden Abyss numbers, but if they werent vgc has uncharted even more undertracked.
God of War: back like six month ago, Santa Monica announced they shipped like 5.1 million copies of GOW3, right now over half a year later, VGC has it at like 4.5 million.
Gran Turismo: back in september Polyphony announced they shipped 9.1 million copies, as of right now VGC has it at like 8.6 million. so nearly 4 month later there are still a half a million games from that shipment on shelves according to vgc
