Blizzard had a good day I would say yesterday with BlizzCon 2019. Opening with an apology with how they reacted with Blitzchung, showing off sequels in Diablo IV and Overwatch 2, showcasing the next World of Warcraft expansion in Shadowlands, and detailing more features in Hearthstone.
While I don't know too much about the IPs other than Diablo, I think most everything looked pretty solid. Yes, Diablo IV is what I am most excited about and it's going to be a while before we get our hands on it, but at least it's coming.
If you missed the opening ceremonies, you can catch its entire presentation below. It's a good watch I say and one that's definitely what I think most people wanted from this kind of event.
