Every game boost the hardware sales a little but if you are trying to say substantial boost then i don't know anymore because the game is coming to 3DS too(First BTW). 3DS is cheaper and have a better library of games,so the casual/mass market will probably choose the 3DS,but the Nintendo Hardcore fans probably will get the WiiU version.
The same happened with Titanfall,people thought it would make a Skyrocket boost on Xone sales and that was not the case(Xone actually sold less Week by Week in march than in february).Older consoles with better library and price caniballize the new console's hardware boost unless the new console have the "Hype train" like PS4 is having.
