Lack of 3rd party Wii U Software in the top 75 World Wide, what does it mean?

Anecdotally: I went to a store here in town. They sold Wii, WiiU and 3DS primarily (its a toystore). They had no 3rd party games on sale for WiiU, except Skylanders Swap Force, Disney Infinity, Sonic Lost World, and Rayman Legends. That was all they had.

However, they had tons of 1st party software.
