An official and extended trailer for Zelda Skyward Sword has been released by Nintendo. This trailer is highly impressive and shows a lot of new game plot ideas.
The trailer continues from the last one shown at E3 last year and shows how Link and the other citizens of Skyloft get around. Link is seen flying on board a giant bird along with a female companion (Zelda maybe?). That girl is swept off her bird and attacked which is probably how the game’s quest begins.
