Well, Dukusword sort of got the scoop on this one, but:
- Many more new races in addition to the Mogmas and the penguiny thing we saw in the E3 trailer.
- Ghirahim is following you when you're in the Sky Temple.
- There's a bit of mystery behind why Link, and presumably Ghirahim too, can't find Zelda. Hmmmm, this implies that there will be some near misses for Link in his search for his dear friend. What is she up to? (My hunch is that she has some sort of religious significance i.e. the chosen one blah blah blah).
Bonus Note: Bill Trinen confirms that there is a master document that lays out what the Zelda universe sort of is and how the games fit together (he didn't say timeline, he said document). Rightfully so, Nintendo feels that releasing the document would restrict their creative freedoms to make additions or subtractions to the canon.
That is all.

They just gave the people eight hearts so they wouldn't have to worry about dieing, same reason they gave players a whole arsenal of red potions
Dude, that's the sword and it's treasure sensing abilities.
I apologise for use of the word "dude".
