That video shows the advantages of motion control and the disadvantages.

Some subtle observations:

-the hit boxes look fairly large
-there are never any moments where the cursor is every steady or still

Advantages motion controls have over a mouse or analog stick:

-it looks easier to make large sweeps across the screen
-in some ways they are more organic since they seem to replicate a real gun; this may be better for games like duck hunt which is essentially a play on skeet shooting

Onto point one of the advantages, I've seen creative solutions for PC gamers. Mice have adjustable DPIs, so you can increase the DPI for twitch movements and drop it back done. I knew a guy who would make the DPI very high for high sensitivity when he was running in Counter-Strike. When he needed to shoot people he would notch the DPI back down. I've tried this set up and found it to be too cumbersome.

Skeet shooting simulation =/= first person shooter. If you add in elements like strafing, I suspect overall precision will go down. Again, the Wii may be better at handling sweep movements, but I still question surgical-like precision.

All-in-all I think you provide a fair counterpoint. And simulation type games would be more fun on the Wii than on a classic mouse or controller. A Wii hunting game or Wii duck hunt would be very fun.

Just compare the Duck Hunt video to the Counter-Strike video I posted, and I think you do see differences with hit-boxes, keeping your cursor stable, and twitch-to-precision movements. The Wii video you posted never slows down, it's a stream of quick shots being fired. You can hide big hit boxes in a stream of action like that.
