Seems someone at Blizzard thought a Zerg rush was coming because the video is out right now for your viewing pleasure. While watching the commercial you will see some familiar stuff, but the rest of it is brand spanking new. The game is shaping up to be one of those games that is well worth the long wait that we all had to endure.
My Take:
After watching the commercial, I really wanted to hop onto the beta and play the multiplayer. I need the game to come out now so I can lock myself in my room and come out like some craze Korean player that hasn't seen the light in days. One thing did bug me about the commercial; Why did he say Macintosh instead of Apple... Hmmm? Enjoy the video.
