Thanks to the comment from South for letting me know about this one.
TNT has picked up Southland. They will air all episodes that have been produced, this will include the 6 unaired episodes so far. They will air all the episodes already aired as well. Depending on how this goes for TNT will decide whether or not production will start again.
Even if no new episodes get produced it does give you all a chance to finish the whole show. Episodes start airing January 12th at 10 pm.
