I searched but couldn't find anything, also this is on the official Wii site, which lead me to believe it may already have been posted.
Anyway here's a vid of a dude using the Wiimote to swing links sword in a fight, looks pretty cool!
The one thing that I'm worried about is that it seems there's some lag between when he swings the wiimote at the start of a combo... It's not really much, but if reaction times are a big thing in this game it could be a bad thing.
Also at the end of the video, it seems if you swing the wiimote twice during the spantime of Link swinging the sword once, it queue's up the other swings and then continues doing them even if you're not swinging the remote, interesting... Looks like it'll take some getting used to, but it should be pretty damn cool!
