Just a heads up:
It seems like a new update (free) for Arma 3 is launched here in November.
The Nexus update is slated to arrive in November. It will introduce "significant improvements" for features such as stamina/fatigue and protective equipment, among other things. The Nexus update will also add an updated version of Arma III's End Game multiplayer mode that originally arrived earlier this year. On top of that, the update will include an in-development version of the game's web-based social service, Units.
In Q1 2016 they'll release another free update which will feature a 3D-editor. And finally in Q2 2016 they'll release a DLC. If you follow the source you'll also see a roadmap for the future A3 updates.
