Update 8 (10/24/2012): Nintendo has confirmed that the game has sold 3.25 million WW including digital. If we go by VGChartz's numbers, that means the game has sold more than 500k on the eShop.

Question. Is nintendo using shipped or sold units this time? I imagine if sold then 4m shipped/digital. If not then I think the shipped/ sold gap = digital numbers.
