Not sure if anyone else on the forum here has stumbled across this particular reddit page, but if not I highly recommend it. They page is an excellent resource for finding vods from tournaments (both ongoing and completed ones), and everything is listed in such as way as to avoid spoiling match results... hence the name.
At the moment I've been watching a lot of vods from Homestory Cup 5, and a small tournament put on by Dignitas called the "Reverse Race" tournament. The idea behind that one, in case people haven't read anything about it elsewhere, is that you have to switch races with your opponent. The obvious exception being mirror matchups, for which they have some crazy formula to determine which player plays what race.
