Why hasn't Nintendo revealed Super Mario Maker's worldwide sale numbers??

I think it probably hasn't reached 1 million yet. Judging by Japan performance it probably sits somewhere around 600 - 700k right now, which is decent but not a runaway hit like Splatoon or Mario Kart was.
If I remember correctly Mario Kart reached it's 1.2 million on it's first weekend in about two days and Splatoon was a special case because while it had an amazing launch for a new IP it has even more amazing word of mouth and legs. These games sold/sell extraordinarily well, Super Mario Maker probably sold only good so far.

We have to wonder whether Nintendo depleted their marketing budget on Splatoon or they spent just as much on SMM.
