A new teaser trailer was recently posted for MapleStory 2, which actually features some of the monster art images revealed thus far for the sequel. It is developed by Nsquare (a team formed by NCsoft and Nexon), and expected to be the major highlight product this November at G-Star 2014.
Taking place long before the current MapleStory, Nsquare has confirmed that updates for the original MapleStory will continue, and both games will run together at the same time. MapleStory 2 is a 3D title, hence purists who prefer the classic 2D side-scroll design may not take a liking to it.
