Buy season 1. Based upon the recent chat with Warner Brothers, a season 2 DVD release is entirely based on sales from season 1. If you're holding out and waiting for another season to be released, they don't care. Sales must be good for season 1 to continue. Look at Night Court, no more releases are planned because sales from season 1 of that show were bad.
