It could easily have that much of a discrepancy.
Remember Wii Music in Japan?
Correct me if I'm wrong, but the official PAL charts, and UK charts all showed that Motorstorm: PR didn't sell very well in Europe, so it's not like VGC is doing something that's unprecedented.
So there are 2 possibilities:
1) VGC is undertracking it in America, where, by some reason, it's sold much better than we think
2) Retailers over-ordered the game.
I'd vote for #2, because it's not like Motorstorm didn't bomb in Japan or Europe. Could VGC have undertracked it slightly? Sure, but as far as I know, we don't have any extra info to confirm it. Chalk this one up as being over-shipped.
But at the same time - Maybe retailers believe that it'll sell well going forward into Christmas.
Back from the dead, I'm afraid.
