At this stage this is unconfirmed but
this website gives the Australian release date as the 28th of Feb. Also the guy in my local EB store told me that he doesn't
think that they will be supplying the DVD as the game will be sold for only $79.95 (for furriners, thats 20 bucks cheaper than normal Xbox games).
I've emailed Alf to get a confimation/denunciation on those details so we shall have to wait and see.
