Sony, Nintendo and MS don't have sales trackers guys.

So when they reveal black friday sales, they mean shipped. It doesn't mean they all sell, and since NPD track sold-to-consumers, there can be some difference here and there, since it's not likely they have sold every single console shipped.

Only Wii U number can be considered accurate, imo, since it's was sold out during that week.

You're wrong. Those Sony/MS/Sony statements for Black Friday were all based on NPD data.
