The PS3 Slim should be in stores this week, if it's not there already.
US - Batman: Arkham Asylum - Collector's Edition is $99, which includes color character encyclopedia, a behind the scenes DVD, exclusive DLC, and a 14" Batarang with stand. I want to make fun of this so much, but I can't deny the desire to throw a Batarang at some one, just one time. Hope they don't break easy. Game is supposed to be superb.
Europe - Invincible Tiger: The Legend of Han Tao - Batman: Arkham Asylum - King of Fighters XII - SuperCar Challenge
For Zack Ryder's theme - I found one on Youtube but it's not complete. I looked on Google and found that its a Jim Johnston original, so finding it online before it's on a WWE The Music soundtrack may not be possible.
