On 1:1 motion sensing. Yes the Wii can do it, when showing Mii's on screen. Can it do it whilst showing something a bit more complex? I don't know.
Also there's the issue of kinematics. Look at the Harry Potter wand video where he follows the motion of your pointing direction with his wand. Notice the rubbery arms. That's because, in order to get a 1:1 correspondence between pointing direction and wand position they have to overcome the fact that you're not actually the character and the motions are simply scalable. They could build a very, very complex model of arm movements that can accommodate the 1:1 correspondence, but that's not practical, so they just take a few rigid points on the arm and make everything else rubbery.
Finally, how much can you actually move the Wiimote in, say, 50 milliseconds? In that 50 ms, what can you do? You can change the orientation of your movement, slightly. You can change speed, slightly. You may even be able to change direction slightly. However, at least 75% of the course of that motion can be described by a vector that takes into account only speed, direction (in terms of left to right etc) and orientation.
I'm not talking about having motion mimicking a button press, but 1:1 is excessive and impractical.

A thought: why are Lucasarts so hesitant on Nintendo consoles nowadays? A conflict like the Nintendo/Squaresoft war of words?
Because, since the demise of their adventure game arm, Lucasarts are all about shiny graphics.
