NPD and VGC are the same, but the NPD has better sources to extrapolate from. The only real 100% accurate data is Sony's (and the others) shipped figures.

Anyway, 0.1m out is within the desired error. It's fine


You're right. NPD and VGC strive for the same goal....so why introduce a totally irrelevant figure into the mix?

The only thing that the shipped figure does is tell you your hard ceiling figure. It has some small relevance to retail sales, but there is potential for a massive buffer between the two...
