alright, i understand where people are coming from with the whole "the girl is the sword" deal, but i just can't agree. it's strait up the Queen of Faeries. the look is VERY clearly that. yes, there are some similarities in look, but at this point it's speculation. there is very little reasonable doubt the girl is not a faerie. keep in mind he ALSO has a shield. an older Link is a PROTECTOR Link.
anyway, i'm thinking
that Miyamoto and Aonuma tackle between OoT and WW. would put some continuity with the Faerie Queen design and even if this character has a connection to the master sword, i doubt the sword = the girl. mainly because there's never been much of a manifestation in terms of persona for the sword. ever. i would think she's more of a guardian if she's directly connected at all.
