I genuinely don't understand why DK hasn't shown up yet, though.
Like, if it wasn't moving a lot of hardware, I'd understand that. I suspect the game will be selling to people who already own a WiiU thanks to the Christmas push with the NSMBU bundle and SM3DW.
But then, why aren't these people pre-ordering it? The only reason I can think of is because they know there will be an abundance of stock when it releases. But still, the same goes for most games yet they get hundreds of pre-orders.
