Uhh... NO? Move only goes 1/60th of a second between recalibrations, meaning that any drifting is corrected WELL before it becomes noticeable to the human eye. Wii has to go much longer between checks. So long that massive drifting will occur. Also the video you see there is hard to gauge how 1:1 the accelerometers even are. You can't see his hand in the full motion and you don't get to see what happens when you rely on the accelerometers alone for more than one slow swipe, so that video is not going to alleviate any concerns.
Besides, if you read the
pdf manual on their site, you'll see that they confess that it's not good enough for more than one gesture at a time due to accelerometer drift--- kind of hypocritical considering they were just claiming "full 1:1 3D tracking" a moment prior.
Yes but that's exactly the problem. With time the accelerometer's positional estimates decrease in accuracy so much that they become dislodged from the true 3D position, and this would frustrate a player incredibly, so devs don't even TRY it with the Wii except for slow, calm movements like in WSR archery.
