I'm fairly certain NL is undertracked. 

Take the US weekly on black friday for example. 

15	Super Mario 3D World (WiiU) Nintendo, Platform	113,245	1,100,287	54
16	Mario Kart 8 (WiiU) Nintendo, Racing	106,285	1,281,125	27
18	Nintendo Land (WiiU) Nintendo, Action	99,648	1,738,886	106

These numbers are inconsistent. This would mean that 130K Wii Us(over half) sold on black friday were either the regular SKU, or the skylanders bundle(unless there is a bundle I'm not aware of that doesn't include Nintendo Land. Which would be the mario+luigi bundle, but I don't see Mario U anywhere near the top 30)

So back to Nintendo Land. Super Mario 3D World sold ~7K more than Mario Kart 8. Most of this was probably due to the bundles, on both sides really. So why is Nintendo Land so low in comparison? 

But back to the original question, can Nintendo Land pass up NSMBU?

No, unless Nintendo keeping bundle it

Which seems to be their intent.

Nah, only sold that much because it was bundled, NSBU will remain the systems top seller for a while

I guess not, unless they keep bundling it until the end of the generation.

I'm more intrigued by 3D World > Mario Kart 8.

But you did find something very interesting. Maybe it's a way ioi tracks bundles that we don't understand? Cause if you combine MK8 and 3D World, it is a more fiting total.

Yes, and then you would need to also add a lot to NL, but that doesn't seem to be the case.

Maybe, if they suported it with:

- DLC: New maps for every game
- Amiibo Support ( i want Nintendo to also do this on their past games)

Probably not, seems a pretty big climb even if it is under-tracked

No. I don't think it ever can.
