In total sales, Skylanders is far behind. Mario is second only to Nintendoland, and a close second at that. I agree it's odd to see Skylanders higher this last week, but it won't have nearly the legs that Mario will.
That said, I wish NSMBU a longevity as strong as the DS/Wii games since it totally deserves it - it's the best 2D Mario game since the Super Nintendo (my opinion).
EDIT: Ah, I made the same mistake as the OP regarding this last week's global sales (Skylanders Wii vs WiiU). Damn power of suggestion... :P
