SMG2 and M&S 2 won't be attracting many new owners at all.
NSMBWii will, but I'd wager a lot of Mario fans already own the console for SMG, Super Paper Mario, M&S at the Olympics 1 and 2, Mario Super Sluggers, Mario Strikers Charged, Mario Party 8, Mario Power Tennis, Mario Kart Wii, Super Smash Bros. Brawl, Dr. Mario RX, the Virtual Console Mario's and a big backlog of GC Mario's from those who already owned a GC and moved on to Wii.
NSMB had a bigger impact on the DS because it was the first original Mario platformer released for the platform.
