According to the Korean website MTN.co.KR, Nexon, N.C., and Blizzard Entertainment have partnered in collaboration to develop together the StarCraft IP for mobile devices. Allegedly, Blizzard Entertainment has been developing an unannounced Overwatch MOBA for mobile. Nexon, N.C. is in negotiations to publish it, limited to service Korean and Japanese markets. While not specified, this opens the door for Blizzard Entertainment to handle the US and Europe markets for the Overwatch mobile game, and in theory, to partner with publishers in China (if approved) and abroad.
