"and you need the pad for the best gaming experience with some of the big games on the 3DS."
Needed for the best gaming experience? Could be, but I am not convinced at all at this stage. I see it not that differently from the CC Pro - some people swear by it for certain games, while others swear for those same games by the Wiimote + nunchuk combo, and I expect the same to happen with this as well. We'll know more once the pad is available and these games actually come out.
