ROTF has shown to us combiners of various shapes and forms. The Twins, Reedman, Devastator and Jetfire parts to Optimus Prime which is pretty much like a Scrapmetal donation to Megatron. The Arcee trio was originally conceived as a combiner. The first movie's gimmick was transforming and reformatting. The second that and combining. Now given the precedents do you guys think we'll see more combiners in TF3?
