Honestly, I think Super Mario 3DS will probably be the best selling 3D Mario yet. It's seemingly pushing for retro appeal with the blue sky / rolling green hills setting and return of raccoon suit. About time they unseated Mario 64's record.
Skyward Sword I think will do less than some expect... 2nd Zeldas per system never do as well (AoL, MM, ST, etc) and it's peripheral dependent, which may inhibit some sales. 5-6m seems like a good safe guess though, provided it has good critical response and word of mouth.
