1up was recently able to talk with Xbox Live Arcade Group Manager Greg Canessa about the plans for the service in the future. According to Canessa, Microsoft really wants to commit to having new content hit the Live Arcade every Wednesday. While they have only announced titles through August, their plan is to get 50 titles available on Xbox Live Arcade by the end of the year. With the current 20-something titles available now, this would mean that nearly every week will bring a new game to the Arcade. Canessa also indicated that Microsoft is working with over 100 independent game developers as well as most of the major studios for Arcade content. Included in the following waves of titles will be Small Arms by Gastronaut, targeted for this fall. Other potential titles include Mutant Storm Empire and Popcap’s Heavy Weapon. Questions about a new Geometry Wars or an Arcade title from Bungie were met with a strong “no comment.”
