As I said in the December NPD thread, I don't consider NPD to be 100% correct ever nor or they they gospel. However, I've followed NPD for a very long time and understand their system and believe them to be within the 90th percentile of accuracy. I also believe VGC to have very solid tracking abilities and for the most times also within that 90th percentile of accuracy. Of course I'd suggest waiting til Nintendo financial reports, but whatev.
