The New Super Mario Bros. series sells so much more than the 3D Marios that I think it's just that simple -- Nintendo wanted some of dat NSMB audience. Unfortunately I think they've kinda run the NSMB formula into the ground by not improving it enough.
They got carried away with the "see? People don't care about graphics, just keep giving them Mario with minimal presentation and they'll eat it up like candy!" formula and it's failed them at the worst possible time (trying to ignite 3DS sales in the West while trying to also launch the Wii U).
