The only thing we can do is wait and pray that it DOES come out in December, which is highly unlikely.
What I'm guessing (and this is just completely out-of-the-blue) is that the "XBOX 360 version" will be shipped down here aswell, and the PC version will come out along with it. And of course, it will be cross-compatable.
Now if this does become true, then I'll be shocked. But one can only hope, yes?
