With February's NPD numbers upon us, Nintendo's Super Mario Galaxy 2 has joined a prestigious club. The portly plumber's Wii title has now crossed the 5 million sales mark. Nintendo notes that the Wii has now amassed nine titles that have passed 5 million in sales, which it says is "nearly twice as many 5-million sellers as competing current-generation consoles combined." The company added that Just Dance 3 is quickly approaching the 5 million mark, with 4.61 million copies sold to date.

On the handheld front, two other Mario titles, Mario Kart 7 and Super Mario 3D Land, both moved more than 100,000 units. In addition, Nintendo notes that Pokemon Black and White have surpassed 4 million units in combined sales.

In hardware, Nintendo sold 228,000 Wii consoles, 262,000 3DS units and 135,000 DS units.

Update: It's actually Super Mario Galaxy, the first one, that just hit this sales milestone.
