There is rumor going around that NPD may not release the numbers of Wii Fit as a software unit (i.e. will not be reported in top 10 if it is in top 10 software for a month) because it may end up being counted by NPD as a peripheral and therefore be eligible for the top 10 software chart. This is just a rumor that is going around currently and does not affect the stock very significantly at all, but it does highlight that numbers in the U.S. for this title may not be as available for revising estimates as if Wii Fit was counted as software. I personally doubt that they will not count Wii Fit as a software title because NPD already has counted Wii Play as a piece of software and the main value in that case is the Wii-mote and not the game.
