So i just found this in an Argos Catalogue... Now, this could just be some place holder Images (as Grimlock is sporting his toyfair colours, having said that though he does seem a little different...Bit more black on him maybe?) however usually on the Optimus Photo of the same pose, he has a red shield....or am i just imagining things?
These are simply the original Hasbro stock photos shown during Toy Fair. Optimus Prime's shield was apparently originally yellow, seen in one of the vehicle mode stock photos and on the prototype shown during New York Comic Con 2013. Apparently the robot mode stock photo was photoshopped to give the shield the final product's colors, but somehow Hasbro UK provided Argos with WAY outdated stock photos. Case closed.
