Oddly enough, the first one popped up in the top 20 NPD for last month, looks like about 80-85k units?
Well, not too odd because Nintendo seems to have FINALLY decided this game is worth marketing. Hopefully they are learning their lesson and realizing that they can make unknown franchises big by pushing them big... don't always have to rely on Mario / Zelda / Wii *insert something here* games to be their big sellers.
Rhythm Heaven looks like it had a solid debut as well, should be another slow burner.
GTA CTW still up there. Not bad.
