RE4 is one of the greatest video games ever made. Really paving the way for a better generation of gaming.  The over the shoulder view will remain in RE5 and RE5 will incorporate a new gameplay element.  Something about light and dark areas of the map , the light areas reveal you more and you are more vulnerable or something.  The RE5 trailer looks awesome, sure to be a great game.RE4 was revolutionary in its mechanics, the over-the-shoulder view and new aiming system really brought you into the game and character, let you experience the game as  never before.  The storyline is obviously a precursor to a bigger, continuing storyline as well.  I can't wait for the RE5!
