Halo 4 GOTY Edition release?

There hasn’t been much said about the release of GOTY Edition apart from the date which of course is the 8th, but will there be a worldwide release?

I’m going to assume that the entire world will have it by the 9th.

So would I but our Games store down under hasn’t got any future orders and its not on the system either, and when went to pre-order it on the Microsoft store, it was region locked to the US. So either it’s only going to be available in the US or the rest of the world is not going to get it till much later.
