So what if the promo pics have it? The release is like a year out. The proto may be held together with poster glue and duct tape. A large portion of the time the proto articulation is not added in yet. And even if it where a completed production figure (it's not) just becuase they don't demonstrate every single feature in the promo pics doesn't mean much. Claiming it doesn't have a feature based on pics of the prototype a year before it is scheduled to ship is silly.
Im starting to think your brain may be held together with poster glue and duct tape. Ill speculate whatever I feel like speculating and could care less whether you think its silly or not. Anyways we'll see who's right once it comes out buddy.
