Some interesting stuff there.
Apparently, they hadn't agreed on doing an orchestrated score at all, and then Miyamoto just dropped that bomb at the developer's meeting about it. Aonuma was like "Really, we can do it?!"
LOL Classic Miyamoto, forcing Nintendo's hand in order for us to get a better project. Now they HAVE to get it approved.
I've heard sooo many stories about Miyamoto doing sneaky stuff like this during development, I think it's awesome on his part. The dude purposefully doubled the size of the dungeons on the original Zelda by submitting the dungeon plans folded, got someone else to convince Aonuma to try putting M+ on this Zelda after they had initially given up on it it, and now he pretty much forced Nintendo approving getting the orchestrated score into Skyward Sword.
Can't imagine Nintendo without him, but it's great to see that Zelda's got a master in Aonuma.
@Faron, I hadn't thought of that until you mentioned it. Your are right, OoT HAS to be Ganondorf's first appearance in the supposed "time-line" as he's just a desert thief prior to the events. No way Ganondorf is in this game. Maybe we'll get something about those three Goddesses from OoT. Something about the creation of Hyrule.
