Blizzard made a terrible decision when deciding how to name their next BlizzCon but certainly won many hearts over by announcing that will not require payment to watch.
BlizzCon is usually an event that has tickets for both physical presence and watching it online. However, BlizzConline will be different. Running from February 19, 2021, it will be free to watch for everyone. The information comes from J. Allen Brack himself, as you can see in the video below.
He walked through Blizzard franchises' bright moments in the Freeside Chat, possibly hinting at what might be featured during the online convention. One particular detail that stuck with the fans was his outro, where he said "En Taro Adun, friends".
This is a line from StarCraft universe that serves as both a salutation and battle cry. It means "In honour of Adun", a revered Executor from the Protoss lore. Given the implications, SC fans started speculating they might actually get some news about their favourite franchise during the clumsily-named event but keep in mind that there is no official confirmation yet.
Brack did confirm more info on Diablo Immortal will become available but Diablo fans are probably hoping for more reveals from Diablo 4.
Another takeaway is that the video featured Overwatch soundtrack prominently, hinting we will get more info on Overwatch 2 by the time of or during the event.
Considering it will be almost a year since the last hero's release by that time, we will be long overdue for some fresh content.
