Or maybe it's because people assume that Wii U games can also be played on the next Nintendo console (like GameCube games can be played on the Wii and Wii games can be played on the Wii U) so if they already have a Wii, they wait for the next console.

And Xbox One and PS4 have a different target audience, and sadly most gamers like the type of games that are Xbox One and/or PS4 exclusive shooting games and it seems like most people just care about online multiplayer.
