As developers within Bohemia is moving to other projects the development of Arma 3 is coming towards an end. It's likely that the Tank DLC will be the last one. They have opened up for third party developers to pitch ideas for potential DLC but there is no guarantee that anything will come from it. While offical development may stop it also means the game will stabilize making it easier for modders. It's also the modders and the many strong communities within Arma that makes sure the game will last for many years until it's finally replaced by Arma 4. While sad to see development stop the possibilty that they are starting to work on Arma 4 gives for a bright future. Arma have been my favorite game series for many years now and it looks to be for many years to come. I just wish we would do more with it.
