Final Fantasy 13 will tear this "record" apart.

Listen, by this point it should be obvious that the metric being used here is different from the metric being used for front-loaded JRPGs. The point of this is that a 2-D Mario Platformer had a staggering launch in Japan, especially given the degree of legs that these games traditionally have in the region.
No one cares if it didn't sell as much as Modern Warfare 2 (nice pick there, you had to choose the one game that makes Halo 3 look reasonable in terms of standards), no one cares if it didn't sell as much first-week as DQIX, no one cares if FFXIII will beat its first-week numbers. This is about Mario. It's being compared to New Super Mairo Brothers on the DS because that's the most direct parallel that can be drawn this gen, and that particular game outsold any other property mentioned so far in Japan.
New Super Mario Bros Wii is huge.
