Hey everyone! :)
I just like to give you a link to the youtube channel of HDStarcraft he's a commentator on both the original SC and the SC2 Beta on the battle net and he's posting footage of SC2 daily. He's videos are really fun to watch very interesting.
If you can't wait for the beta and really want to watch some footage of the high-skilled players on the Bnet feel free to take a look :)
