With Chris Metzen back as the creative director of Warcraft, it is no surprise Blizzard has a lot to reveal about it. A new World of Warcraft expansion will almost certainly be among the reveals, as will something new for WoW Classic. According to the diagram, Hearthstone also has something new to demo, and Warcraft Rumble will probably be released sometime around the convention's launch as well. Without a doubt, BlizzCon is going to be huge for Warcraft fans.

Despite this, Diablo 4 Gold and Overwatch 2 fans will have plenty to look forward to at BlizzCon as well. Though little is known about what Diablo 4 will show off there, Overwatch 2 will be revealing its new tank hero and has a second hall dedicated to the Overwatch World Cup. Unfortunately, StarCraft does not appear to be at BlizzCon, so fans shouldn't expect to hear anything about it this year.

It is no exaggeration to say this could be Blizzard's most important BlizzCon yet. In addition to being its first post-pandemic convention, this will be the first BlizzCon since its lawsuits and controversies, many of which involved misconduct from developers during previous BlizzCons. All of Blizzard's IPs are currently contending with problems of their own, and this is the first BlizzCon to not sell out its tickets immediately. If Blizzard wants to regain the good faith of its communities, it likely needs to nail this year's BlizzCon.

Diablo 4's upcoming Season of Blood is crucial for the game's future success after a disappointing first season and declining playerbase. The lack of meaningful endgame content in the Season of the Malignant was a major issue for players, and Season 4 needs to address this to keep players engaged. Blizzard may need to have a backup plan or fast-track substantial new content if Season 4 fails to recapture the interest of players, and BlizzCon 2023 could be a crucial opportunity to generate hype for the game's future.

There's a lot riding on Diablo 4's upcoming Season of Blood set to begin later this month after an underwhelming first season left many players disappointed in the live-service component of the game. Diablo 4 launched to high praise and strong sales back in June of this year, but its playerbase has dropped off in the time since due to some controversial updates and a lack of worthwhile content in the Season of the Malignant. The Season of Blood will hopefully turn things around for the game going forward, but Blizzard may need to have a backup plan in place.

Live Diablo IV Items -service games live or die by the quality and consistency of their updates in order to keep players engaged and wanting to continue playing a game long after release. The Season of the Malignant left a bad taste in the mouths of a lot of Diablo 4 fans after it increased the late-game grind without offering enough of a payoff to justify the tedium. If Blizzard is serious about keeping Diablo 4 alive with content for years to come, the Season of Blood needs to wow fans, or else they better have another plan up their sleeve to entice players to stick with the game for the long haul.
