The problem I think with Wii Fit Plus and Wii Sports Resort is they're pretty much direct sequels/expansions to games that people who already have a Wii already own.
At least Mario is new for a console and no Mario has ever had 4-player either. Monster Hunter 3 did its job as far as I'm concerned, it boosted the Wii much higher for a full month and paved the way for other core games to follow behind it (like Samurai Warriors 3, Tales of Graces, etc.).
