The answer to your question is for you too look at the user base of the 3DS compared to the user base of the Wii U. Same reason why some games wont come out for the PS vita but for other consoles.
Another problem with Nintendo (not sure if its true) is that they been banking on their franchise games such as zelda, mario, and pokemon to carry them that they pretty much alienated a lot of the 3rd party developers. Now that the Wii U came out that can play the same games as the PS3 and 360. Nintendo wants these developers. But they have either lost the relationship or never established a relationship with these developers.
