I was watching clips of DOTM, and I saw the scene where the autobots were in the NEST base where Optimus was giving the silent treatment, and then I watched a clip of the Mexican standoff scene. I quickly noticed Ironhide's robot form was different in the two clips! In the NEST hangar, Ironhide has the very "stocky" form that looks like a big chest with legs, arms, and a head on it, but in the Mexican standoff scene, Ironhide had longer legs, a torso, chest etc. basically a nicer balanced out robot form giving him a taller and more proportioned neater appearance standing up opposed to his usual bulky ball with limbs form. If you pay attention you should definitely be able to see the difference. I want to post pictures or links but we can't but keep this in mind for when the DVD comes out on dvd next week or you can look it up on your own on youtube. His robot form cgi is different in the two scenes!
