"Legion" will raise the level cap to 110, add a new class called the Demon Hunter, as well as a new PvP honor system, artifact weapons like Ashbringer and Doomhammer and class order halls.

The expansion sees a demonic invasion bigger than the war of the ancients, streaming into Azeroth through a portal in The Tomb of Sargeras. Players will have to search for the Pillars of Creation to close the portal in The Tomb of Sargeras, taking the fight to Gul'dan and his armies.

Weapons customization is also coming, with players able to unlock different colors.

The last "World of Warcraft" expansion, "Warlords of Draenor," was released in November 2014, just over a year after its announcement at BlizzCon 2013. Also known as Warlords or WoD, it takes players to the orc home world Draenor, as it was in "Warcraft 2: Beyond the Dark Portal."

"Warlords of Draenor" raised the level cap from 90 to 100 and introduced garrisons, which players can build and upgrade themselves. WoD also opened up eight new 5-man dungeons and two raids.

The WoD expansion sold 3.3 million copies in the first 24 hours, bringing the declining "World of Warcraft" subscriber numbers back up to 10.5 million from around 7 million.

With the new expansion Blizzard is surely hoping to draw in new subscribers and players that have let their subscription lapse.

"Warlords of Draenor brought more players back than any previous expansion, and showed that even long time lapsed players will return when the right content is offered," said Blizzard Entertainment CEO Mike Morhaime during the Q1 2015 earnings call.

Despite players coming back to the game initially, subscriber numbers have since dropped to the lowest in years, with Blizzard announcing during its Q2 2015 earnings report on Tuesday that it now has 5.6 million -- meaning it lost 1.5 million subscribers in Q2 2015 alone.

On Wednesday Blizzard announced new content – including two new characters, a new map, mounts and skins – for its MOBA "Heroes of the Storm." It also confirmed during its Q2 call that "StarCraft 2: Legacy of the Void" will be released soon.

With all of these announcements coming out before BlizzCon on November 6-7, it's hard to imagine what big announcements Blizzard could possibly be holding back. Bets are on for more details about "Legion," and "Heroes of the Storm."
