My aunt & uncle run a Mom & Pop store, "The Gamecube Hut", and sold 80k WiiU within minutes of opening.
Reading that article, it doesn't give the other Wii Canadian sales, but does mention that's basically the months of December and January. Doesn't seem to be flying off the shelves.
Canada Population - 34,482,779
World Population - 6,973,738,433
6,973,738,433 / 34,482,779 = 202.24 Canada's worth of consumers worldwide.
202.24 * 35,700 Wii Mini = 7,219,968
Assuming the remainder of the world has identical buying habits to Canada, Nintendo should definitely release the mini worldwide.
