Just got him in today. VERY cool. I'm not going super overboard on pics, since we've seen a lot already, but I'll do my best to get some shots of member requests if you have any. Truck mode is nice, a lot more accurate than the first one. He's slightly shorter at the top of the cab, but about 1/4" longer overall in truck mode. About the same mass as the first toy. The "Racing Truck Sounds!" we saw mentioned on the previous box pic have been removed. No sounds that I can find in vehicle mode, and there are none listed on the instructions either. UPDATE!! I found the truck noises. They aren't mentioned on his instruction sheet, and the picture on the box made it look like the button should be located in the blue section on the side of the cab. Turns out it's a tiny hidden tab on the battery compartment you need to push, seen circled in yellow below: It's just an engine noise, nothing as exciting as the "racing truck noises" listed on the package, but it's there. The sound lasts as long as you hold the button down. Video update for the vehicle noise is here: Here's a quick shot of the undercarriage to fulfill a couple of requests: Transformation is crazy. That Trailer hitch is actually how his waist plugs into the torso. The entire front underside of the truck is actually his FEET, folded up and extended. The grill of the truck is once again the underside of his feet. Watch the video review, it's CRAZY. The engine and cab form his torso and arms. Snapping the waist into the torso activates the transformation noise. A REALLY neat transformation that pays off in Robot mode: He's a good inch and a half taller than the first movie's leader class figure, and overall a LOT more screen-accurate. And they both have swords! A quick side comparison: The red is about the same color on the new one as the older version. The flash is making it look pinker, but it really isn't. You can see in the side shot of the truck modes that the reds both turned that weird pinkish color in the flash. And you can see how his forearms are actually a much darker red in this rear shot. The back is a lot cleaner this time, and more screen accurate as well. Just an all-around excellent figure. The swords are activated by a button on each arm. And flipping down and pressing on the same piece as the first movie's figure causes his chest to flex witht eh mach alive gears and he says "I am Optimus Prime!" If it's NOT Cullen's voice, they got a good imitator. But my money's on the fact that it's actually Cullen. As for the Mech Alive, when you push the button that activates the voice effect, the chest flexes and the gears inside rotate a little. It's nothing super impressive, but it's there. There are also some bits in his upper arms that rotate as you move his lower arms, much like the ones on Sideways. Here's some close-ups of his head/chest: Video review is available here: YouTube - ROTF Leader Class Optimus Prime Short Version: Super Awesome, Buy on sight! Some posed shots for those asking: A running shot: You can see he's balanced on one foot and his toes: Balanced on one foot: Taking out Stockade: Optimus Victorious!!!!
