actually, there is a spot, kind of secluded away from the area of the final battle where the wave of brutes are coming in from on the landing pad that you can find his body, its right before you go to take control of the cannon after emile dies its located all the way on the right in a dirt and hill area. i would never have seen it if i didn't stumble on it. its kinda sad actually, he's propped up on a rock with holes everywhere in his armor. i could be mistaken but thats what i saw.
If this has happened then I will play that mission again to see for myself, i dont have a camera hooked up to my 360 but i will tell you if i see him...
