Wow, I just noticed that in the scene were Link gets the Hero's cloths, he has the Skyward Sword, we can see that it's green, but he doesn't have a shield. I think this matters because this is an actual cutscene in the game (why would they put fake cutscenes in a trailer?). So Link doesn't have the Hylian Shield when he sets off to Hyrule! Wich now makes perfect sense that it has the triforce on it! Here is the FABULOUS! trailer...
