Update # 2

Blizzard Entertainment provided a few glimpses into the GamesCom 2015 since May.

“Blizzard has an amazing show planned for you at gamescom 2015. With just over two months to go, we’re really looking forward to this year’s epic event, and we want to share our excitement with you.” — source: https://us.battle.net/wow/en/blog/19800550/blizzgc2015-social-media-contest-win-a-trip-to-gamescom-6-9-2015

“Looking for your next shot at playing Overwatch? Make like Reinhardt and charge hammer-first into gamescom 2015, the world’s largest interactive entertainment trade fair taking place August 5–9 at the Koelnmesse in Cologne, Germany.

This year’s gamescom marks the first time Blizzard Entertainment’s 6v6 shooter will be playable publically in Europe—so if you want to get in on the action, assemble your team in our official booth located in Hall 7.

In between battles, Hall 7 will also host a variety of activities around all of Blizzard’s games, including developer signing sessions, showmatches, quizzes, community contests, and more. On top of that, the latest versions of Heroes of the Storm, Hearthstone, StarCraft II, and World of Warcraft will be playable on more than 500 game stations in Blizzard’s sector of the show.”
