Nintendo failed at casualizing this game. You have to die 8 times to get the super guide. How many casuals are going to die that many times before they lose interest?
So, given that NSMB is a hardcore game and is on the Wii it will probably struggle to break 300k and Nintendo will say they are "pleased" with the sales but they'll really be lying.
