I'm one of the people who brought ArmA2:CO just for DayZ because it's different - it's intense, it's teamwork if you want it, and it's survival. Now this may make me part of "hype" joiners, and I'm okay with that. I know someone who brought it because of the hype and hasn't touched it since, and inevitably, as with all games, at some point the active players will decline; It's just part of the development lifecycle. Based on the community and the active development both on this mod and on the beta ArmA 2, I don't believe this decline will be any time soon. Is it going to disappoint? Only to the people who don't do their research and find out what the game is (thinking it's L4D for instance) and as bobgold mentioned - they will leave but the mod will keep evolving. Likewise with people who don't like change - for them sometimes it's easier just to delete the game and quit rather than finding a new playing style. Good riddance to them imo. So am I worried? Hell no. I'm excited to see where Rocket and the developers are going with this, adapting my game play with new patches and generally trying to outplay myself with each life. And with this strong of a community and popularity I would be surprised if there isn't a ArmA3/standalone in the future. Fact.
