I think they intentionally leaking these stuff to get more people to watch BlizzCon, maybe there's another special announcement coming up that isn't leaked yet?
I wouldn't be surprised if half of the fake pics are also the devs. I am sure reading the hype threads is good fun for them.
Nah, it's a bit more than that - Diablo 2 Remastered was leaked by Metro, who leaked Ashe last year and whose info on Overwatch 2 and Diablo 4 that he leaked alongside Diablo 2 this year seems perfectly in line with other leaks.
I'm on board with the theory that it's not that the helm takes him over but rather that the blue eyes come from him tapping into the helm's power. What's he doing? Who knows. Raising Galakrond? Fighting Sylvanas? Opening a gateway to Bastion? Stubbing his toe?
Wanna bet he raises Galakrond? Every villain needs his Dragon by his side, just like Arthas had Sindragosa. It will mirror WOTLK cinematic as well.
