Blizzard announced on April 30 that they will not be attending Gamescom 2019.
"As part of a renewed effort this year to maintain our focus on development, for our current games and our future projects, we won’t have a booth at Gamescom 2019," the announcement stated, "The show is an important one for the European and global gaming community, and we’re going to miss meeting players in Cologne this year."
Gamescom is arguably the biggest gaming trade show in the world, pulling 370,000 visitors in 2018 (compared to E3, which drew in a little over 69,000). It is a major event in the video game industry, and in the past, Blizzard have made significant reveals at Gamescom, including the first post-release Overwatch map, character shorts - such as Mei’s and Bastion’s - and World of Warcraft expansions, not to mention the first consumer appearance of StarCraft 2: Heart of the Storm.
In February of this year, following a shocking number of layoffs at Blizzard, the company announced that there will be no “major frontline releases” in 2019. This may explain why they’re missing Gamescom this year. However, luckily, their absence should only be for this year, as the post states that Blizzard are “looking forward to returning to the Gamescom show floor in the future.”
