Wheeljack looks great, my only issue with him is that if we get a toy of him (which is pretty damn likely if he appears in the show) we won't get an Universe toy of him for a while, but I think I can survive. a good Animated Wheeljack is better then no Wheeljack!
As for Perceptor, well, he has never been a huge favorite of mine, so I am not as excited about him as Wheeljack. However, I do like him, except they really need to re-work his head and make him look less silly...
