Looks like somebody dropped the ball over at the famously secretive Blizzard Entertainment, because the above video is popping up all over the internet. Given the proximity to E3, it seems likely that they were planning to unveil the teaser at the big show. Fortunately, you don't have to wait that long to enjoy this awesome Heart of the Swarm CG footage. We still don't know for certain when the game is releasing — although, a supposed leak a little while back suggests Q4 2011 — but the video should tide you over until it does.
