At the end of the Season 12 Official Trailer, there’s a brief scene on Watchpoint Antartica, where a large Mythic-looking sword cuts down into the icy ground with Juno in the background saying “What was that?!”. From the pattern of hero releases, I think its pretty safe this new hero will be a Tank.
Who will be this new sword-wielding hero? Any ideas who it could be?
Nah, its shield hero racoon warrior girl. Also play warcraft
you have probably never played World of Warcraft 
(another blizzard game). that’s frostmourne, the lich king’s sword in WoW, which became epic especially for the adventures of Warcraft 3.
it’s highly likely that it’s the teaser for a new “”“collab”“” (i doubt it can be called that, it’s a blizzard game, right?) with world of warcraft. that sword? it’s not hard to imagine who the character is who puts his weapon on the ground between the emotes, right? Reinhardt.
I have heard of Warcraft but Im not really familiar with the characters. Although, that sword really does look familiar now!
A collab/crossover? Thats pretty cool! If the skin really is for Reinhardt, that will make for an interesting mash-up of sword and hammer.
Yup, it’s a teaser for the next round of Blizzard “crossover” skins
Immortal Orisa, Blackhand Doomfist, Illidan Genji, that sorta thing.
