How different will this Ocarina be?

I was well into this one earlier when I saw the snippet about Ocarina that's doing the rounds. Luckily, it didn't really affect the bulk of the video (if anything it strengths it) but I figured I'd bring forward the release. Of course it's taking forever to process so now I kind of wish I'd waited as it's going to be so late (here) by the time it's ready. Oh well.
