Along the way we did receive a concrete release date for the game, which was previously revealed to be in September and later reported to be August 30 for North America. We're told the Windows version's release date in North America (which is listed as September 6 on every retail listing we can find) is being pushed back a few weeks to September 27th, and that while an OS X edition is still planned, its release date is now TBD.
