MKDD didn't save the (already very cheap) GC, MK8 and a pricecut won't save the Wii U.

MKDD was still financially rewarding for Nintendo. Roughly half of the GameCube owners in the world bought that game. That's a higher attach rate than any other Mario Kart game since.

We are talking about saving the Wii U's sales numbers, not Nintendo's pockets (which are in good shape). While the game might (probably will) have a nice attach rate, it will take a herculean effort to dig the Wii U out from where it is atm.
