But it's actually a good reason to share DLC.
It prevents either console from getting too much attention. It means they can't just pile on DLC for the Wii U version while shrugging their shoulders to the millions who bought it on 3DS (Which has over twice as many total sales than the Wii U's copy).

It's not taking away anything, ultimately. There are 4 DLC stages, and all but one (Suzaku Castle) are just N64 stages. The variety of stages is still there. But boo fucking hoo. Wii U doesn't get Peach's Castle all to itself.
