The annual event will again be held at the Anaheim Convention Center in California, this year taking place on October 21 until October 22.
Fans can expect the usual rounds of discussion panels, competitive tournaments and hands-on time with some of Blizzard's upcoming titles, it says.
We'll also no doubt get plenty of cosplay, some of it sexy, some of it downright odd. Have a look at what last year served up.
"We look forward to holding another exciting BlizzCon this year, filled with some great entertainment and competition, as well as the latest news about Blizzard games," said Mike Morhaime, CEO and cofounder of Blizzard Entertainment.
"BlizzCon is built from the ground up with our community in mind -- we're pleased to be able to host an event where players can come together to have fun and celebrate their passion for gaming."
