I can tell you that LARGE vendors like Sony or M$ get whatever sales data they want from companies that are reselling their products.  It is actually extremely helpful in helping both companies keep products in stock for customers.  I think Sony or M$ could tell you almost any given day how many systems are sold if they wanted to.  Their just isn't a lot of benefit to give the copetition the info.  All of these 3rd party companies put togehter the info for sale to competing companies.  Sony doesn't need NPD to tell them the PS4's sales, they want the sales numbers of the XB1 and WiiU.

One might get a different impression when reading NPD threads on VGC.

Goes to show you the knowledge base of most of the people here.  They take tidbits of information and jump to lots of conclusions.  I don't bother to normally argue too much in the NPD threads, as most people have a console wars agenda and don't really want to talk sense.
