Shockwave looks amazing!
Grimwing looks pretty cool too! Sort of a griffin 'o doom or something.
I'm actually not really that impressed with this version of Ultra Magnus. The shoulders looks good but it looks to busy with the wings from the BH Optimus mold. I think I'll probably stick with the PRiD version...which I really like.
Ratchet...well...his colors look pretty terrible. Also, his chest details look strange and his face doesn't really look like Ratchet to me. I hope the good doctor doesn't get horribly mangled by a beast and this is what we get. I'll reserve judgment but I'm a little disappointed since he is my favorite 'Bot on the show so far.
