PLEASE Bohemia, communicate with us. The release was a disappointment, but we can be patient and wait for ArmA 3 to get better. But we need some positive feedback, the feeling that you are aware of ArmA IIIs shortcomings and ready to fix them in time. A "roadmap" would be a very good solution.
But right now I hardly see any reactions from BIS, instead signatures that try to tell me that the community is supposed to finish the game. That does not inspire trust for the future.
