I don't see anyone buying a wiiu without the gamepad, espcially since you need it to power the machine.
My personal issue with selling the wiiu is what about the games i have atm
I have 3 digital games, Xenoblade X, Mario Maker and Zelda WW (on an external HDD)
and 1 Physical game Zelda TP
I wish they would confirm if there is BC or not for NX
