Between the slew of pictures from practically the same angle and that these are mockups/prototypes, it's hard to tell. Was anyone who was there or read it answered on some forum or is there some better picture out there that definitively shows that Shockwave actually has two hands and the gun is interchangable/an accessory? The only photo I've seen of a better angle comes from the pics from the gallery that was put up here which shows Shockwave from the side, There we can clearly see that something swivels out from the forearm, much as the fist does on the other side. However, is this a hand, or is this part of the gun assembly to get into the final and correctly transformed position as seen in the official photos, So we can see that properly transformed the gun ends up flush, but is this because it's all "one piece" that is manipulated around thanks to the hinge joints and swivels and only looks like a hand in that one picture, or is it a seperate piece that fits into the hand to sit flush and cover the hand, much as FE Prime has his weapons which cover his fists? In other words, is the cannon like (for lack of a better example) Animated Cybertron Megatron or Hero Optimus Prime's or like WFC or Voyager Prime Megatrons? The vehicle mode pics don't help, as unless I'm very much mistaken the hands end up on the underside in jet mode, so I can't tell if it's a swivel out or seperate piece.
