Just go back after a 2 day trip with no Net access.
I was looking at the pics and the upper piece of shoulder armor is a completely different shape, its more "square" from the pic, instead of the curve like the one on the right.
Even the lower piece is different
good eye. but i think maybe the one on the left was a promo shot and they made changes before they released it.
To me the pic is PS'ed, when they layered Batman over the Joker shot they distorted it horizontally making the head seem wider and the chin seem shorter.
