I do like the new colours but I'm not so sure about buying them. It'll depend on the price point ultimately. I like both figures enough since they're from Cybertron but if I'm going to be asked to pay $60 a pop from TRU for repaints, no thanks.
JD, I think Wing Saber is a better toy than the Sky Shadow/Jetfire mould. The problem with Jetfire mould is there's a massive opening behind his chest that really stands out. His arms are quite limited too.
Wing Saber is a pretty decent figure with an arsenal of weapons and I think you'll like how the blades and weapons all translate from alt mode to robot mould. They all fit nicely into the alt mode without seeming cumbersome. The transformation on Wing Saber is pretty interesting too. My main complaint is he's top heavy, very hard to get into a good pose.
