Could Wii's success bring more than one Mario platformer like the NES?

There are already 2 :P Paper Mario, not really a RPG mostly platform and Mario Galaxy. But if you say a full 3D adventure game... I HOPE SO!

 Actualy I would rather have one 3D Mario and one 2D Mario on the Wii. So give me a NSMB spinnoff to Wii.
