Wii U + NSMBU + NSLU + 3D World = $360 (2 games & DC)

3DS XL + NSMB2 + 3D Land + Pokemon X + Animal Crossing NL = $360 (4 games)

2DS + NSMB2 + 3D Land + Pokemon Y + Animal Crossing NL + Zelda ALBW = $330 (5 games for less)

With Holiday deals for the 3DS as well. Here lies the problem. Wii U has a similar library to the 3DS and is more $.

I agree with you though, consumers should worry about the games not the sales of the system.
