Those aren't great numbers, but Mario games tend to have legs. Wii U is in tough in Japan, hasn't even NSMBU only sold about 600k there? We know the Japanese pretty strongly prefer 2D Mario.
I think Super Mario Galaxy 3 is in development either way already for November 2015, my worry is that Nintendo will switch it to the larger userbase of the 3DS and leave the Wii U hanging. That would piss me off.
