We've just gotten word that Battlefield 3 has broken street date. According to a store rep from JB Hifi Chatswood, Target started selling the game early, which has resulted in JB Hifi also deciding to sell the game a day ahead of its release date tomorrow.
We expect all other specialist retailers to follow suit and will update with more news as we get it.
UPDATE: Both EB and GAME have not begun selling the game at this point, but a store rep in JB Hifi Kotara informed us that they've just received word that, since one of their competitors have begun selling the game, all JB Hifi stores can now follow suit.
UPDATE 2: EB Games has now confirmed via their twitter account that they are now selling Battlefield 3.
UPDATE 3: GAME has also now confirmed that they are selling Battlefield 3.
