Yesterday devs published this post and two things are certain for at least 50%.

1: Varian Wrynn will get Overwatch skin, because this swords looks definetly like Twinblades Of Fury, which Varians wields.

This may suggests, that Varian will get Overwatch skin, associated to Volskaya Industries, that ones who maked Zarya gun and were introduced in Sombra announcement trailer.

2: Firebat incoming? If we look at at the back, we see an robot arm. Since for now leaks didin't lied and after Stukov we get Garrosh and Kel'Thuzad. I think now for 50% is Firebat. Other option is second Overwatch map in HOTS.

As we can see, Firebat got somekind of robotic arm, but that is not in case.

Today is another HGC games, and between first and second match, is time for revelation. Looks familiar to Garrosh announcement somehow...
