[Source] Uncovered by a fan-site, the developer of Tree of Savior, IMC Games, will be making a presence at G-Star 2014 with a booth in the business (B2B) hall. They are certainly there to look for new business opportunities, since NHN Hangame is no longer the Korean publisher.
Other than Tree of Savior, WolfKnights is also a major MMORPG currently in development. I doubt any announcements will be made during the period until a publisher is confirmed, but then again IMC Games might really publish the games themselves with a global server. We shall see.
