THQ has announced that a playable demo of their new GTA-like game, Saints Row, will be available on Xbox Live on August 1st.  Saints Row will be available for purchase on August 29th exclusively for the Xbox 360.  This demo release date looks doable, unlike the recently delayed PREY demo for several reasons.  The demo will be included in the Official Xbox Magazine which means a much larger lead time is needed to get it into the magazine. THQ will also be offering a demo on June 24th in Anaheim California which could easily be the same one we will see on Live August 1st.  THQ has more info and screenshots on the Saints Row official site.
