Nothing surprising. Nintendo asked (maybe?) to some third parties (which I honestly doubt) for the development of the Wii U, but not every third party. Plus, they wanted to convice them to develop for it once the console launched or just few months before its launch.
Seems like this won't be fixed ever.
