Wii U (especially WiiU) and 3DS have some serious attach rates

[PAOerfulone]

Wow. Those are some incredibly insane attach rates.
And A LOT of Wii U and 3DS games appear to be greatly undertracked here. Either that or they have very high digital sales - (But this charts needs to find a method of tracking digital sales so that all this confusion can be avoided)
And some are slightly overtracked as well.
Nintendo Land close to 5 million and ahead of Mario U?!?
Mario 3D World is close to 4.5 million and ahead of Smash Wii U by quite the margin. So that appears to be undertracked.
Pokemon X/Y is at 14 million!
Mario Kart 7 is close to 12 million!
Omega Ruby and Alpha Sapphire are already past 10 million and ahead of Mario 3D Land (which is overtracked)
New Mario 2 looks alright w/ digital.
Animal Crossing New Leaf is just insane. Though I wouldn't be surprised if it has that many digital sales.
Smash 3DS looks fine.
GO LUIGI'S MANSION!!! Closing in on 5 million, and raising my hopes for a Luigi's Mansion 3 in the future!
No really, I hope Luigi's Mansion becomes it's own recurring franchise! Luigi deserves more love than he's getting!

I wonder how Fire Emblem: Awakening must be doing, I hope it's close to or surpassed 2 million units at this point.
