I don't know, VGC tends to overtrack games like this. I'd wait a while (probably NPD) to be sure, though I definitely hope it did do well. The game looks great.
Too bad I didn't bring my Wii to college, hopefully I'll get to play it around Thanksgiving.
As for terms, I always thought it was
pre-order: manufacturer to retail
NPD: tracks retail to consumer
So by pre-orders alone, we can't easily judge if NPD is undertracking or not.
