While the official site has nothing new to offer, 2P.com found a recruitment listing for a director to handle Blizzard's entire eSports program. This listing specifically mentions the upcoming MOBA, showing that the game has not been completely abandoned. This should give fans some hope that the game might still see the light of day sometime. And perhaps when director is found, we'll hear even more news on the progress of the game.
