So hasbro & takara is able to add a new head sculpt when doing repaints. yet we don't get any added/retooled parts that allow more poseability on a previous TF toy mold. example: doing a remold giving ROTF Leader sized megatron's huge death arm a elbow bending joint. doing a remold that adds sideways splitting hip joints to the armada voyager seekers joints. doing a remold that gives armada tidalwave bending knee joings doing a remold that gives armada megatron,walking hips & bending knee joints. doing a few remolds that give certain TF toys articulated fingers & rotate wrist joints. I noticed that the most extensive re-sculpts appeared to be the beastwars 2nd takara cyborg beast molds. recently the most extensive re-sculpt appears to be the ROTF Voyager sized fallen blue & purple recolor. the toy appears to have a new head sculpt that pops on/off. a new accessory staff. and what appears to be a new set of hand that are different & have more poseability.
