Developer is not a part of the pie. They take a contractual bite from the publisher's slice, whether it's a preset amount they receive upfront, or a variable amount dependant on sales.
As far as this game, I believe its content is far outside of an average WiiU owner's comfort zone, and will sell accordingly, between 200-300K. However, I believe that's enough for it to be profitable, as it is probably not a terribly expensive game, and its marketing budget will most likely be in single digits...
