5th job to be released this year.

I don't see why they couldn't make another big bang, it's been almost six years since big bang hit korea and that came six year after maplestory came out plus I can see from what the devs are saying and doing that they also want to(with the skeleton and they wanting to remove cap and other stuff), the only thing that makes me think they might not is that I doubt they have the resources they had back them or if it's a good idea to invest it on a pretty much dead game(although I think MS2 is doing worse than MS1 back there iirc).
