If they had some kind of attachment that could hook the gamepad to your forearm then it could be intersting, but really how often do you use the sheild that you would need to do that? If there was another game where you had a gun and had the gamepad on your arm. You have to look at the gamepad to select modes and change settings on your future suit and the nunchuck was used to move and the wii mote to shoot your gun. It could be interesting.
I always felt like they could have mapped the sword swing to the right analog stick. I mean there's no need to have the Right analog be the camera. Nintendo's been working without it for years and all of their games have worked perfectly fine without having the player have manual control over the camera. Thus with the second analog you could do all the sword movements movements you need.
A quick flick in a direction and he will slice in that direction. Hold it in a direction and he'll charge for a stronger attack. Pressing R3 will do a sword thrust. It's pretty simple and with Nintendo land you already know how the bow, sling shot, and other projectile weapons will work on the game pad.
Those who want to use the Wii mote should be able to use the option as well.
