It's a year later than originally planned, even with the single-player campaign cut out to become free post-launch episodic DLC, but Arma 3 finally has a release date. Bohemia Interactive today announced the military sim will launch for PC on September 12.
Bohemia is still selling the game discounted with early beta access. The regular edition is $45, or for $60 the Deluxe version adds world maps, a guide, the soundtrack, and the original Arma: Cold War Assault (formerly known as Operation Flashpoint). Either gets you instant beta access and the full game on Steam.
Here's a recent video from ShackTac's own Dslyecxi having a gander at Arma 3's helicopters:
