Battle.net notes that Heroes of the Storm will turn one next week, also announcing that next week is when the Hell Billie mount gallops into the Nexus. They say that they will celebrate with a bonus XP event, a first anniversary portrait, and a new bundle. Word is:

It’s hard to believe that we’re approaching a full year since the official launch of Heroes of the Storm on June 2 of 2015. Since that date, we’ve introduced fifteen new Heroes, four new Battlegrounds, tons of new skins and mounts, and much more! To celebrate this momentous occasion, we’ll be introducing some exciting new promotions to the Nexus.
