Okay, I am in the USAF, stationed in Korea. I bought the game at our Base Exchange, since we get most new releases on the same day as they release in the States. It is currently about 5pm on 20 October here, which means it's past midnight PST. When will the game unlock for me???

I would guess it unlocks at 12:01am GMT on friday, that's when it unlocks for the rest of the world.
