Looks like different goggles and the lights are in a different position Edit - nevermind, the left side is exact concept art from TF4. The head does look a bit different on the right though. Ever so slightly.
OH good, he's basically the exact same as before. Should mean Hound is also going to be similar. I like the new goggles and headset are more noticeable, and his face looks slightly different in detail, but not shape. Whoever thought I'd be happy over something as fundamental as consistency? Minor alt mode and paint job tweaks don't bother me, but I really didn't like how Op and Bee were totally different for some reason.
