I know it's in October and that it will be international, but what is the exact release date (if there is one)
There is no exact release date yet. All we know is that it will be in October, but I will update once an exact date has been confirmed.
EDIT: The exact release date has been confirmed to be October 12, 2013.
As of now, we don't know exactly when it will be released.
The official Date has yet to be announced, although it has been revealed to be sometime in October.
I predict somewhere in the middle of October, like BW.
