Bohemia Interactive announced via press release today that ARMA 3 has been delayed from it's original 2012 release.
"In what might be described as an eventful year, Bohemia Interactive has decided to postpone the release of Arma 3. The additional development time enables the project to reach its full potential, with the studio expecting to finalize their release plans in the new year."
Eventful is a bit of a understatement as the game has seen a project lead change and two of the studio's developers have been in jail for 3 months in Greece after being accused of spying on military bases on Lemnos while on vacation. The press release also quoted Joris-Jan van 't Land:
The new release window of Arma 3 has been set for 2013. Joris-Jan van 't Land: "I hope this update provides some answers regarding the status of the project. We're currently sorting the specifics so we can deliver a more complete announcement at the beginning of next year."
