Update: Blizzard has confirmed release dates for both characters. Chromie arrives on May 17. Medivh drops on June 14. The latter is based off his later, repentant design. That means he isn't in it for the damage, but rather serves to soften enemy opponents and support allies.
Original Story:
Blizzard has been teasing reveals for at least one more Heroes of the Storm character for a few days now. A video that appears to have been posted early points to two new characters coming to the Nexus, new skins, and more mounts.
With the Duncan Jones’ Warcraft movie just a month away (check out an interview with him on this week’s Game Informer show), a focus on that franchise fits. The two heroes are the Gnome Chromie and the accursed human Medivh.
Additionally, the Widowmaker tease seen at the end of the Tracer reveal trailer has been confirmed as a skin for Nova. Don’t worry, though. There are plenty of Overwatch characters that could find a home in the Nexus.
You can check out the full reveal video showcasing upcoming skins and a mount here (until it’s removed, anyway).
