Wii U is now 1 month old and has sold 1.8 million units. How is it doing?

I thought it would have a better start than the Wii, but fade off really quickly in Q1 2013. A big launch with poor numbers following shortly after for a while.

Expected NSMB to do launch wonders.
Thought supply wouldnt be a problem, while the Wii was sold out everywhere.
It had, or seemed to have, a healthy launch library.

Expected ~2.3 Million in a Month. In all honesty though, over 1.4M is still really good.
