Why is GAF treating Pachters Wii U prediction like its real sales data?

Pachter's numbers ARE based on sampling of retail stores. They're too close to be just a guess.

So basically they do what VGC does. If you disagree with this you have to disagree that VGC is meaningful as well.

Thing is, nobody seems to be making a big deal out of VGC's numbers, but somehow many people are making a big fuss over Pachter's.

Then again, humans are naturally more attracted to bad news, so I guess nothing surprising here.
