I say Mario Kart Wii will outsell NSMB, unless NSMB get's bundled again then it won't but I don't think that will happen.
Also NSMB might get a boost by the Wii version but I don't think it will get too much of a boost, because MKDS was also advertised at the end of the commercials, let's see if Ninty will do the same with NSMB.
