Since the whole purpose is to know how many units are in customers hands all units need to be tracked. After truly to MS sold units are what are shipped and those are not reported by VGC other than in news reports and forum threads. I am willing to wait for adjustments to occur when shipment numbers are reported and sales numbers are adjusted to reflect well if X shipped Y units through Z date we estimate W units on store shelves so Q units are in customers hands.
Its libraries that sell systems not a single game.
