The rumor mill is showing a video that is supposed to be the ending of the next installment of StarCraft 2, Heart of the Swarm.
There are some details in the clip that help prove it could be genuine. The watermark of production studio The Third Floor, which includes Blizzard and StarCraft 2 as its client and project respectively, is clearly seen on the bottom right. There’s also the amount of effort that Blizzard is putting into getting the video removed from YouTube and the like.
Keep in mind that this is a work in progress so the voices don’t match lip movement and everything is in relatively low quality. Needless to say, the clip is full of spoilers galore. Watch it at your own risk.
Real or not? Your guess is as good as mine.
