We honestly don't even know where to begin with this week's PSN update -- it's like staring down the business end of a five-foot Philly cheesesteak. There are demos for Dead Space 2, Mass Effect 2 and LittleBigPlanet 2. Not interested in demos? Well, there's RISK: Factions and Echochrome 2 for PS3 and Valkyria Chronicles 2 for super cheap on PSP. It really is an amazing update for the holidays. Check out the full PSN update after the break. (Philly cheesesteak not available, sold separately.)
