IIRC, the PS2 version is coming out in Oct. 2005 (just in time for Halloween )
About RE4, I'm playing it and it's awesome, I really recommend it. Don't deny yourself this awesome game for any longer
About the game, imagine Metal Gear Solid meets RE with the camera behind the character (plays really similar to 1st person shooters). The graphics is top notch, not sure if Sony POS 2 could handle it The game is very intense...try playing the game alone in the dark ;;
