Even though nothing has been said as to when the three heroes are coming, they have published the concept art of heroes many of us have been expecting for months already. Without further introduction, I present to you Lycan, Sylla and Shadow Demon
Hopefully these heroes will be implemented into the beta soon and we may see a rather interesting shift in the current meta game.
Additionally, Valve have stated that they will be releasing a more detailed description of the process that goes into developing these hero designs in the near future.
