Blizzard announces a June 2nd official launch date for Heroes of the Storm, their free-to-play MOBA featuring characters from various Blizzard games that's currently in closed beta testing. Here's word on release plans, which will include a livestream the day before the launch:

Heroes of the Storm will launch with more than 30 playable Heroes and 7 dynamic Battlegrounds, each with unique challenges to overcome—and even more Heroes and Battlegrounds are on the way. Players can customize the look of their Heroes with a variety of skins, as well as switch between a stable of special mounts that help them cover ground on the battlefield more quickly.

To celebrate the launch of Heroes of the Storm, Blizzard will be holding a live-streamed event on June 1 in London, U.K.. Further information will be made available as the event draws closer.
