It has sold over 8million and NSMB DS is a 2D platformer, watch what NSMBWii does.
Galaxy has done very well for a 3D mario and will continue to sell well for the remainder of the Wii's life at $50. Just like Twilight Princess is still $50.
They won't decrease in price until their sequels come and then be combo priced and such.
