No shit, I got all hyped and then they're like "2030 lolololol"
Fuck you!
That being said, do we even know what kind of game this will be? Trailer seemed to have a Helldivers vibe to it - not that I wouldn't mind a Starcraft Helldivers type of game.
Regarding Starcraft, the dude on stage said "open-world shooter" but that's about it. Blizzard isn't known for being super original, so I'd expect some Helldivers-type thing. 15 years after Helldivers happened.
New Warcraft III campaign, yay. It's in Reforged, booooo. Releases today.
The gameplay trailer showed that they're revamping the Reforged graphics to look more like the classic Warcraft III after the backlash for Reforged, so there's that.
