Starcraft II: Wings of Liberty will be getting a new patch today, bringing the game up to version 1.2.1. The patch will bring fixes to the matchmaking in 2v2, 3v3 and 4v4 for people to like to play premades (i.e. with and again you know instead of strangers). The patch also includes some tweaking of the user interface, various levels and the map editor. You can find the full list of changes over at Battle.net.
