Especially since Wal-mart participates with Siras, even with their online sales, but doesn't release any info to the public or NPD. So the guy from Sega is most likely right if he's saying that NPD usually undertracks sales. |
He didn't reference that, or any known data though. If Siras really showed NPD undertracking by as much as 30%, I doubt Nintendo would be using NPD in their IR reports.
