I´m on the forum where the head of the team is talking, and he said that the game is"already profitable", also he said VGChartz is a joke where people just take the data out of their asses, that with better words, but I guess that is another story.

Could you share a link to these comments?

This is probably closer to the real reason. The cost of the extra effort required to get the game to an acceptable level of quality outweighs the profit they could make from the Wii U version.
