According to MMO Culture, it appears that the Korean NCSoft site has been updated with a number of job postings for a brand new "next gen MMO" based on the Aion IP. The game will be built using Unreal Engine 4 and job requirements include using "3DS Max to create character / monster / animation resources for the concept and development environment". But...that's about all we know.
Still, the idea that something-something-something Aion-related is interesting as the now-original game was pretty interesting in and of itself.
What do you think NCSoft has up its sleeve?
