I definitely agree that Nintendo needs to do some physics puzzles. I'm not talking about simple "drag the block to balance the platform", but I mean more advanced physics stuff. Personally, my favorite physics engine is Havok. For those who don't know, Havok has been in Super Smash Bros. Brawl, every Halo game since the second, all Source Engine games, and the list just goes on and on.
The Legend of Zelda series has definitely had its share of very interesting puzzle concepts, and applying physics, such as those of Havok, would definitely add on to the Zelda experience. In general, a great physics engine for Zelda with ragdolls would be awesome. We've seen how the character models work in Skyward Sword, so if they were to actually fall on the ground instead of just do some sort of leap back, that would definitely be quite nice.
We've already seen what wind can do in the Zelda series for puzzles, mainly in The Wind Waker and Twilight Princess. We've even seen puzzles in Wind Waker in which you position boxes to float (Tower of the Gods), now imagine those with actual physics. The WiiU, if I recall correctly, is supposed to have either a dual or quad core processor. If they used Havok, it wouldn't even need that much power to run. So, yes, physics is definitely a good way to go.
