There are many many many companies who rely on NPD data as it has shown itself to be the best source of sales data with extrapolation models that work. In comparison, how many of those companies have chosen to switch to VG?
With results that are wildly off everymonth VG is not reliable. Lowering or Upping your guess the next month to try and bring your overall results inline with NPD does not show equiv tracking but merely defensive manouvering to try and remain relevant.
BTW, the fact that you KNOW about those SONY ads means they got your mind share. Ta da.
