My bad. I completely forgot it was Japanese centric for a moment.
However there was no hardware boost because there was no increase in hardware volume for sale. They were also being held for Golden Week which was from Apr 29 to May 5. The biggest release during that period was Link's Crossbow Training but hardware went up from mid 40's to almost 70k.
MKWii opened to 580k in Japan and such little hardware impact wouldn't make sense unless the volumes were constrained. Even when selling to an already established fan base (like MKWii was) that small of a boost is unheard of. Other big titles selling to already established fan bases have typically still increased hardware pretty decently.
There is one other difference between MKWii and NSMB Wii. I've not known many of my gaming peers that were interested in MKWii that didn't already own a Wii but a lot of my non-Wii owning counterparts are definitely interested in the first 2D side scrolling Mario game on a home console in 14 years.
