i predict the controller will work flawlessly, don't judge a book by its cover. Nintendo used one kill word, that could damage their sales and has some people in doubt. the word is gyroscope, the same thing that condemned Segway 1 to the scrapheap. a few of my friends have had trouble with gyros, but those troublesome gyros are mechanical, and have a set flaw point when it encounters resistance. but Nintendo's new wii, uses optical gyroscopes, which don't break under resistance, because optical gyroscopes use fiber optics to judge distance and movement. if you have ever had a bad experience with gyroscope technology, either blame Sperry, the company that invented mechanical gyroscopes, or don't apply it to the wii.
