I think it was a combination of piracy, the fact that monster hunter tri gave you a whole lot for your money with a lenghty single player and an absolutely massive online play and was released in the same timeframe. Theres also the problem of some gamers that havent buyed a motion plus as the amount of games that use the peripheral is pretty thin so it doesnt justify a mandatory purchase (I know a few) though that could change with the release of Zelda.
