I was commenting more on the visuals than the controls.
A real person holding a sword, or even just having a sword sheathed at the hip, moves and walks with a gait, swings their arms, etc, that is essentially matched by the sword held in his/her hand or attached to his/her hip.
My guess is people aren't going to play the game standing up and walk on the spot so that Link is going to walk around holding/moving the sword with a natural gait.
