DFO, Combat Arms, and Vindictus coming to Steam?

So I hear. I know for DFO the population is absolute crap. There's only one server after ~2 years of being officially out of beta. That's like Maplestory only having Scania for 2 years after being officially released; the Korean version has a good 10-12 servers as comparison. That's a sign how low the population is. More people to balance out the economy would be very nice. Not sure how Combat Arms and Vindictus are faring. But again, more ways to get people into a game helps. Combat Arms probably won't get that many more people, because there's already other more established FPS games, especially Counter-Strike/TF2/Call of Duty/Battlefield. But hey, there's always the curious. DFO is rather niche, so there's bound to be people getting into the game. Vindictus, I can't give a clear opinion since I know nothing about the game.
