In his review he makes note of the differences of this figure to the previous mold, such as a ball-joint neck and remolded roof, doors and bumpers. In his words:
-head: that's the new one from the new ROTF grey version)
-neck plate: new design, lower profile to allow for a ball-joint neck... now the head is more poseable than ever!
-windshield: now solid blue-painted grey plastic
-doors: all new "armored doors" with molded reinforcement plates and rivets... also, the rear doors are no longer attached to the front doors, they're now attached to the roof and they fold up
-roof: for the reasons I just mentionned, plus there are now additional lights and bars attached to it
-rear window: different mold, with new exhaust pipes and bars that fold out in robot mode
-front bumper: totally new design, now removable so it be combined with the missile launcher to form a crossbow
