IGN posted some more supposed Zelda news from some company in Spain, so I doubt it's accurate, but it's interesting anyway. According to the two articles, Link is not from Hyrule, but from a neighboring kingdom and he starts as a farmboy. The world is roughly four times bigger than that of "Ocarina of Time", as well.
Oh, and Link may be able to communicate with animals.
